VP of IBM’s Quantum Ecosystem Development Bob Sutter
Technology moves fast. Scientists are developing the next generation of computing called quantum computing. Over the past year, I have been briefed on what is happening in the field by IBM’s VP of Quantum Ecosystem Development. Bob has had the opportunity to speak with Sutter many times. While quantum computing is not a household word, Sutter shared that it is not new. The origins of quantum computing date back to the 1900s and quantum mechanics.
Quantum computing uses quantum mechanics concepts such as superposition, entanglement, and interference. Yet, these terms are confusing for individuals who are not deeply immersed in physics. Instead of trying to explain this to everyone, I suggest watching this video where WIRED discusses with IBM Research’s Director of Hybrid Cloud Infrastructure Research, Dr. Talia Gerson challenged 5 different people to explain quantum computing. Gersh was previously IBM’s senior manager of quantum research. The video is brilliant.
When the suitor said we could think of computing in two camps, provided an easy way to describe it. Surrey called these camps classical and quantum. The classical age uses what we have today, such as processors, servers on the Internet, mainframes, and high-performance computing. But why did quantum evolve and why do we care about it?
Sutter explained how certain problems could not be solved by a classical computer. Similar to what Gershen said in the video, traditional computing runs out of capacity to solve the problem. In other cases, classical computing takes a long time to solve. So, IBM and others are working on a variety of computers that overcome those barriers.

Why don’t we have it today?
Quantum requires different hardware, software, physical enclosures and a new programming model to run. Quantum computers use quits, which are quantum bits. It is an extension of the idea of zeros or ones, but with quantum, we have more than a binary choice of zero or one. One way to describe it is a game of heads or tails. When a coin is dropped, it is either the head or the tails. However, when it spins before landing, it has neither head nor tails. They are both. The same principle applies to the qubit of computing, which can be in the position of zero, one, or Superposition That represents both. This flexible position provides additional parameters in which to calculate.
If we add the concept Trapped (Combining quits to make their behavior consistent), we can double the power of quantum computing whenever we add another qubit. For example, the system can go from two to four to eight to 16. This declarative growth in computing makes it well suited for solving complex computing problems.
But there are also challenges
In the ideal world, you can create qubits, add additional quits and apply operations (instruction set) to quits to achieve the desired result. However, it is not quite easy. As Scientific Computer says, “Quantum computers are very difficult to engineer, build, and program. As a result, they become handicapped in the form of noise, defects, and loss of quantum compatibility, which are crucial to their operation and yet different Before any ineffective program has a chance to run. ”
Cubits are sensitive to heat and any external interference. Quits must be kept in a cold chamber because heat creates computing errors. For example, an IBM quantum computer sits in a chamber where the temperature is 0.015 Kelvin. By comparison, the average temperature in outer space is 2.7 Kelvin.
Noise can cause some errors that affect the calculation. Some of these errors can be caused by small manufacturer defects, while others can be caused if the system applies too much energy to the quibt. The anatomy of computing carries extra noise from the real world. To do this, you have to do what is called mitigation to reduce it. IBM published a paper in Nature, clearly talking about a smart solution that uses noise to help eliminate noise.
It’s about quality, not quantity
As with older processor wars, it’s easy to get caught up in the discussion of which vendor’s system has more quibet than the other vendor. In Quantum the question should not be how many quits a computer supports, but how many high quality qubits. A good quantum system starts at the device level. Scientists and engineers create qubits for the device, try to minimize errors in each qubit, and optimize how it is connected to other quits. For example, if you used a poor quality HDMI cable, your television would not have a clear picture. It is the same with quantum. Every step is necessary to ensure the highest quality.
Because quantum computing differs from classical computing, quibs require new metrics to measure quality. Sutter said IBM uses a metric called quantum volume (QV) to measure the power of a quantum computer. The QV method gives the ratio of the largest random circuit of equal width and depth that the system implements with high performance. Quantum computing systems with high-fidelity operations operation, high connectivity, large calcified liberated gate sets and circuit-rewriting software toolchains should have high quantum volume. Putting aside the technical conditions, this dialog replaces the number of quits by talking about the number of static quibts (compatibility) that can only communicate with each other like a system. Sutter said IBM has been able to double this power year since 2017.
Given the new state of the industry, it is not surprising to hear that there are differing opinions on the best way to measure the performance of quantum computers. While I can’t comment on the best way to do this, however, sellers must provide a framework to help buyers understand the features of performance and the different styles of measuring them. The use of quantum volume is about to begin to show the influence of their systems by others like Honeywell.
Is there quantum computing around the corner?
Quantum computing is considered to be a technology that is very far away. And, indeed, quantum computing is not around the corner. However, tremendous progress is made every six months. Last week, IBMA announced that by launching a series of new software and hardware technologies to improve overall performance, IBMA has improved one of its 27-quint client-deployment systems to achieve Quantum Volume 64.
Real industries are investing today
Companies like IBM, Google, Intel and others are spending time building better systems and better software. However, this does not happen if they are operating in a research vacuum. Real progress only happens when tech vendors work to solve real problems with customers. IBM offers Quantum Experience, but the IBM Q Network is a commercial version of the program where companies have access to IBM’s latest technologies and support for business strategy engagement.
For example, Daimler has worked with IBM to research how quantum algorithms for chemistry and materials science will support Daimler’s long-term goal of designing new batteries. IBM and Exxon are looking at how quantum computing can improve predictive environmental modeling, and help Exxon find new materials for more efficient carbon capture. Meanwhile, in finance, JPMorgan Chase and IBM are researching methods for financial modeling and risk management.
Quantum Gain vs. Quantum Supremacy
As you read more about quantum computing, you will inevitably take part in the notion of “quantum supremacy”, the idea that classical supercomputers can’t do anything. Quantum computers are powerful enough to complete the calculation. IBM’s suitors talk about establishing quantum advantages as they are more significant. Quantum Benefit is the point at which quantum computers perform certain computing tasks more efficiently (hundreds to thousands of times faster) or at a lower cost than just using classical computing. It’s not for every kind of problem, but it will be the best in certain matters. He believes this could be easily achieved within a decade.
Suite noted that quantum computing is not as simple as manufacturing quibt. He said there is also engineering for science, experimental physics and research. For example, scientists must improve quantum circuits to gain quantum benefits. Sutter expects that in three to five years, we will see early examples of quantum gain. However, this vision of quantum advantage requires hardware, software and algorithms systems, all of which come together.
Advise organizations
Quantum is exciting because it forces people to move beyond the old concept of how to accomplish various computing tasks. Putting the old side aside allows for progressive thinking, which requires companies to make their digital journey to the next level. Like any other IT project, you need a Quantum Computing Champion to explore, experiment and evangelize technology in your organization.
Quantum computing is not something you can pick up on a weekend or at a grocery store. It is a ging tide technique that has been away from widespread commercial use for five or more years. However, an organization should start its quantum computing education today and start defining projects that can take advantage of cloud-resident quantum technology.
Institutions that do this have the opportunity to make progress in areas such as physics and artificial intelligence. Many are already on this educational journey: at the recent Global Summer School, 4,000 people attended workshops and labs to learn about IBM’s open source kiskit development platform.
Individuals can also take advantage of the quantum wave.
The evolution of quantum computing also provides an opportunity for people to engage in learning new computing skills in order to enter the market in its infancy. Since the quantum fundamentals are different from classical computing, it does not require re-learning of previous knowledge or skills.
It’s an exciting time in calculation. We have real problems, such as making vaccines, that quantum computing can help us develop faster and better. Researchers and technology vendors are providing training and training fee access to computing resources that cost billions of dollars to design. Anyone with a desire to learn new skills and skills has the opportunity to participate in the next wave of computing jobs regardless of gender, age, or other affiliation. The world is what you make of it and individuals can use quantum computing to make it better.
