The Advanced Quantum Testbed at Lawrence Berkeley National Laboratory (Berkeley Lab) is a collaborative research laboratory funded by the U.S. Department of Energy to advance quantum computation based on superconducting circuits. The AQT instrument was commissioned as an open platform to explore and define the future of superconducting quantum computers end-to-end, from quantum processor technology to quantum algorithms. In collaboration with AQT’s expert team, testbed users will have full access to hardware and software, participate in its evolution, and advance the science enabled by quantum computing. This is the fourth annual Open Call for user proposals.

Teams from academia, industry, and government laboratories may apply to become AQT users. The length of typical projects is a few weeks to a few months. Access to the testbed and staff is provided at no cost to users for non-proprietary work that will be published in the scientific literature. Information on the current and anticipated capabilities is available on our website.

We offer close collaboration with AQT scientists on the execution of user projects, including guidance on the efficient compilation of quantum algorithms tailored for AQT hardware, optimization of gate sequence selection, novel control sequences for quantum feedback and noise suppression, potential fabrication of custom quantum processor chips, and other areas.

We are committed to serving and helping create a broad quantum computing community and encourage submissions from diverse and inclusive teams.

Projects may be proposed in the following areas:

  • Implementations of Quantum Computation Algorithms or Quantum Simulations
  • Quantum Characterization, Validation, and Control Routines
  • Novel Control Hardware / Firmware / Software
  • Novel Superconducting Quantum Processor Architectures

User projects are typically executed remotely in collaboration with our staff. Starting with this cycle, we are open to on-site access and collaboration on a case-by-case basis.


How to Apply


Access to AQT is provided through a proposal process, and we encourage prospective users to contact us with any questions at The first step is to submit a brief Letter of Intent (LOI) through the online form. The required information for the LOI is described in the Appendix (below).

Based on the LOI reviews, teams will be invited to submit a full proposal, which consists of a 2-page project narrative and up to 2 optional additional pages of figures and references. We will provide access to full proposal instructions, templates, and technical guidance from AQT staff upon acceptance of the LOI. Users may not submit full proposals without an accepted LOI.



Letters of Intent will be reviewed and approved on a rolling basis. We encourage early submission to provide enough time to develop the full proposal.

For full consideration in this review cycle, LOIs are due October 26, 2023.

Full proposals due November 20, 2023.

Notification of review outcome is anticipated by December 15, 2023.

Round 4 User project window January 1, 2024 – December 30, 2024


Proposals received passed the due date may be deferred to later reviews.


Proposal Selection LOIs and full proposals will be evaluated for:

  • Scientific merit
  • Alignment with AQT program goals and utilization of unique resources not available in the commercial domain
  • Feasibility with testbed capabilities and resources

LOIs will be screened by AQT staff. Full proposals will be reviewed by a committee of researchers with relevant expertise in QIS. The final selection of the accepted proposals will be made by AQT leadership.

Required Agreement

A fully executed agreement between Lawrence Berkeley National Laboratory and the user’s institution is required before starting research at AQT. For institutions other than national laboratories, AQT uses a standard Collaborative Research and Development Agreement (CRADA) mechanism. This agreement includes the contractual basis covering the distribution of intellectual property rights. Please contact us with any questions.
