Q & A

  • What is the significance of the announcement IBM is making regarding quantum computing?

    -IBM is set to announce an advance in a new kind of computing, quantum computing, which has the potential to solve problems in minutes that would take today's supercomputers millions of years.

  • What is quantum computing and how does it differ from classical computing?

    -Quantum computing is a technology named for quantum physics, which describes the forces of the subatomic realm. Unlike classical computing that uses transistors with binary states (on/off), quantum computing encodes information on electrons that can exist in multiple states simultaneously, allowing for exponential increases in data processing capabilities.

  • What is the current stage of quantum computing development according to Dario Gil?

    -Dario Gil, head of research at IBM, states that they are at a stage where quantum systems can perform certain calculations that would take the world's largest supercomputers a significant amount of time. Moreover, the technology is expected to expand such that even a million or a billion of those supercomputers combined could not match the calculations of future quantum machines.

  • How does the concept of a quantum bit, or 'qubit', contribute to the power of quantum computing?

    -A qubit, or quantum bit, can hold and process more information than a classical bit because it can exist in multiple states at once, not just on or off. This allows quantum computers to process a vast amount of data exponentially faster than classical computers.

  • What is the role of coherence in quantum computing?

    -Coherence in quantum computing refers to the ability of qubits to vibrate in unison. Achieving and maintaining coherence is crucial because it allows for the control of qubits with an electromagnetic field. However, coherence is challenging to maintain and is fleeting in similar machines, leading to errors.

  • What is the significance of the temperature in quantum computing systems?

    -Quantum computers require extremely low temperatures, near absolute zero, to function properly. This 'deep freeze' eliminates electrical resistance and isolates the qubits from outside vibrations, which is necessary for their control and operation.

  • What are the main challenges facing the development of quantum computing?

    -The main challenges include mitigating errors that occur due to the fleeting nature of coherence, extending the coherence time, and scaling up to larger machines while maintaining the integrity of the quantum states.

  • What is the goal for quantum computing development by the end of the decade according to Hartmut Neven?

    -Hartmut Neven, the founder of Google's quantum lab, aims to integrate all the pieces of quantum computing technology by the end of the decade, suggesting that no more fundamental breakthroughs are needed, but rather incremental improvements to build larger systems.

  • Why is quantum computing considered a potential game-changer in various scientific fields?

    -Quantum computing could provide answers to problems in physics, chemistry, engineering, and medicine that are currently considered impossible for classical computers to solve due to their complexity. It offers a different way to represent and process information, which is essential for tackling these complex problems.

  • How is quantum computing being applied in the medical field, specifically at the Cleveland Clinic?

    -At the Cleveland Clinic, quantum computing is being trialed to model the behavior of proteins, which are crucial for understanding diseases such as cancer and autoimmunity. The ability to model protein behavior in real time could revolutionize healthcare by providing insights into disease mechanisms and potential treatments.

  • What is the potential impact of quantum computing on encryption and cybersecurity?

    -Quantum computing is expected to have a significant impact on encryption and cybersecurity. It is anticipated that quantum computers will one day be able to break existing codes that secure national secrets and credit card information, prompting the development of new encryption standards.

  • What is the current capacity of IBM's Quantum System 2 and its potential for expansion?

    -IBM's Quantum System 2 has three times the number of qubits as its predecessor. Dario Gil has expressed confidence that the system has the potential to expand to thousands, and eventually tens or even hundreds of thousands of qubits, significantly increasing its computational power.
