From classical FLOPS to quantum CLOPS

by

This week IBM Quantum introduced a new quantum computing architecture-neutral performance speed metric called CLOPS. CLOPS is short for “Circuit Layer Operations per Second.” For those of you familiar with measuring the speed of high performance classical computers, the acronym is a nod to the metric FLOPS, or “Floating point Operations per Second.”

CLOPS joins Quantum Volume (a measurement of quantum circuit execution quality) and Number of Qubits (an indication of the size of the problem your system can handle) as one of the three essential ways that we can measure progress toward practical Quantum Advantage. Quantum Advantage signifies the point where quantum computers together with classical computing systems can do better than the classical systems alone.

IEEE Quantum Week 2020
This year’s IEEE Quantum Week is planned for October 12-16, 2020, in Denver, Colorado.

IEEE Quantum Week is a multidisciplinary quantum computing venue where attendees will have the unique opportunity to discuss challenges and opportunities with quantum researchers, scientists, engineers, entrepreneurs, developers, students, practitioners, educators, programmers, and newcomers.

Jerry M. Chow, IBM ResearchThe IBM Quantum team is well represented at the conference with a keynote from Jerry Chow. We also have 7 tutorials and 2 workshops.

Our tutorials are on the following topics:

  • Quantum programming, an introduction
  • Quantum machine learning for data scientists
  • Quantum hardware control: a hands-on introduction
  • Quantum algorithms for optimization
  • Quantum algorithms for chemistry simulation
  • Assessing the quality of qubits and quantum computers
  • Serious Games for Quantum Computing

Our workshops are:

  • Control and design of superconducting qubits
  • Software for quantum applications, algorithms, and workflows

Registration is now open.
