The surge of growth in quantum computing over the past few years 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 supremacy".

The Assessing Performance of Quantum Computers (APQC) workshop, scheduled for September 25-27, 2019 in Estes Park, Colorado, is intended to jumpstart this new field.  The workshop's goal is to bring together experts in all these fields, establish the state of the art in quantum performance assessment, and guide its growth.

Topics and Technical Scope

APQC actively encourages 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.
  • Modeling and understanding obstacles to performance, including
    • quantum noise and errors
    • limits to programmability
    • latency, unreliability, and other hindrances.

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

We enthusiastically invite researchers and stakeholders who are expert and/or keenly interested in these topics to apply to APQC.  Participation is limited to 70 persons, due to space and funding constraints; applications received by August 16, 2019 will be guaranteed full consideration.  Later applications may be considered if space permits.

Location and Venue

APQC will be held from September 25-27 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.

A block of rooms has been reserved for participants at the special rate of $149/night.  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:

  • When your application is accepted, you will receive detailed instructions on how to book your hotel room.  If you need further assistance, please contact us at

  • Sergio Boixo (Google)
  • Joe Emerson (Quantum Benchmark / U. Waterloo)
  • Steve Flammia (U. Sydney)
  • David McKay (IBM) 
  • Adriaan Rol (T.U. Delft)
  • Kevin Young (QPL@Sandia)
  • Yipeng Huang (Princeton)
  • Marko Cetina (UMD JQI)


APQC will begin at 9am on Wednesday, Sep. 25, and end at 5pm on Friday, Sep. 27.  There will be roughly 9 invited talks and 16 contributed talks, as well as roundtable discussions and lunchtime presentations.  Working meals (breakfast, lunch, and dinner) will be provided for registered participants.
