Timeline_AQT_first light

-Prior to the establishment of AQT, Berkeley Lab internal investments seeded the acquisition of a large, 1000 microwatt dilution refrigerator targeting full control of 128 qubits.
-Developed 8 qubit processors with varied topology; gate / readout fidelities > 95%; coherence > 100 μs
-Continuous hardware improvements leveraging wiring for 128 qubits with 99% fidelity
-User program was launched. 20+ research proposals were submitted at the inaugural call (Fall 2020), ranging over a variety of topics: algorithms or simulations; characterization validation or control; ontrol hardware, firmware, or software; processor architectures


-Using circuits to determine quantum capacity: verification/validation, noise detection, suppression, mitigation, noise resilience architectures, and so on.
-Quantum simulation experiments

-Executing algorithms for scientific computation and benchmarking on state-of-the-art NISQ hardware
-Defining the next generation architectures and algorithms via co-design
-Defining the path to operate deep circuits

-The current hardware configuration involves the parallel operation of multiple processor architectures to explore a larger design and application tradespace.
-Continued expansion of quantum processor library available for users
-Increased quantum volume (faster gates, parametric coupling and control, smart compiling)
-Larger numbers of qubits [10-20]
– Additional circuits and topologies – flux-based devices (fluxonium), and bosonic encoded qubits (Kerr-Cat)
-Enhanced control options, including fast feedback – a feature requested by several users.
-Exploration of distributed / modular computing architectures

A Berkeley Lab podcast about the surprising ways that science evolves. In this episode, AQT Director Irfan Siddiqi and Project Scientist Zahra Pedramrazi chat about the current state of quantum computers and explain why the mind-bending theories of quantum make coming to work a lot of fun.
