The Quantum Performance Lab is excited to announce the Assessing Performance of Quantum Computers (APQC) 2023 workshop. It will be held October 2-5 in Estes Park, CO.

The surge of growth in quantum computing since 2014 has generated tremendous interest in a fundamental question:  “How well does a given quantum computing processor perform?”  A new research field — quantum performance assessment — has emerged, bringing together aspects of quantum characterization (QCVV), quantum algorithms, quantum error correction, experimental qubit design, quantum computer science, and quantum computational utility.

The first APQC workshop, held September 25-27, 2019 in Estes Park, sought to jumpstart this new field by bringing together experts in all these fields and establishing the state of the art in quantum performance assessment. APQC 2023 seeks to bring together the same community — four years and one pandemic later — to discuss and shape the future of quantum computer performance assessment.

Topics and Technical Scope

APQC 2023 will host talks, discussion, and debate on topics including (but not limited to):

  • QCVV techniques for characterizing errors in 1, 2, or more qubits.
  • Use of quantum algorithms or algorithm-like circuits to probe high-level performance.
  • Comparing the performance of quantum processors to their classical competition.
  • Development and use of well-motivated benchmarking suites.
  • Software for quantum performance assessment (new at APQC 2023)
  • Modeling and understanding obstacles to performance, including
    • quantum noise and errors
    • limits to programmability
    • latency, unreliability, and other hindrances.

The focus of APQC is on digital (gate- or circuit-model) quantum computing, but interesting connections to adiabatic, annealing, analog, or other quantum computing models are welcome.

Registration and Abstract Submission Information

Registration for APQC 2023 is now closed.

Location and Venue

APQC will be held from October 2-5 (Mon-Thurs) at the Ridgeline Hotel in Estes Park, Colorado. Estes Park is the gateway to Rocky Mountain National Park, one of the most scenic locations in the United States, and the workshop dates coincide with the peak of fall color.

The nearest airport is Denver, Colorado (DEN), and Estes Park is roughly 90 minutes by car from DEN.  Here are some links to further information about what there is to do and see around Estes Park:


Here are some options for getting to the Ridgeline Hotel from the Denver Airport:

  • Rental Car
  • Estes Park Shuttle ($95 per person round trip)
  • Ride share, e.g. Uber or Lyft, (~$80 each way)

Hotel Reservation/ Booking Information:

Instructions on how to book a room at the Ridgeline Hotel were emailed to accepted participants. If you are an accepted participant and are still seeking to book a room, please contact for assistance.

Invited Speakers

APQC 2023 will host 6 invited and plenary talks presenting some of the most exciting developments and accomplishments in quantum performance assessment from around the world, as well as lunchtime talks presenting the perspectives from US DOE and the startup ecosystem. Confirmed invited speakers include:

  • Jordan Hines (UC-Berkeley)
  • Charles Baldwin (Quantinuum)
  • Riddhi Gupta (IBM)
  • Michael Gullans (University of Maryland)
  • Akel Hashim (UC-Berkeley)
  • Dripto Debroy (Google)
  • (Software plenary) Anurag Saha Roy (U. Saarland and Qruise GmbH)
  • (Lunch Perspective) Claire Cramer (DOE Office of Science, Advanced Scientific Computing Research)
  • (Lunch Perspective) Joseph Emerson (Keysight) and Adriaan Rol (Orange)

Schedule & Agenda

APQC 2023 will begin at 8:45am on Monday, October 2, and end at 4:30pm on Thursday, October 5.  The program is now posted, and includes invited talks, contributed talks, roundtable discussions, lunchtime perspective presentations , and a special session on software for quantum performance assessment. Working meals (breakfast, lunch, and dinner) will be provided for registered participants.  By popular demand (after APQC 2019), Tuesday morning/afternoon will be talk-free to encourage scientific collaboration in the Rocky Mountains.
