Improved belief propagation is sufficient for real-time decoding of quantum memory
Tristan Müller, Thomas Alexander, Michael E. Beverland +4
We introduce a new heuristic decoder, Relay-BP, targeting real-time quantum circuit decoding for large-scale quantum computers. Relay-BP achieves high accuracy across circuit-noise…
Encoding a magic state with beyond break-even fidelity
Riddhi S. Gupta, Neereja Sundaresan, Thomas Alexander +10
To run large-scale algorithms on a quantum computer, error-correcting codes must be able to perform a fundamental set of operations, called logic gates, while isolating the encoded…
Summary: Chicago Quantum Exchange (CQE) Pulse-level Quantum Control Workshop
Kaitlin N. Smith, Gokul Subramanian Ravi, Thomas Alexander +14
Quantum information processing holds great promise for pushing beyond the current frontiers in computing. Specifically, quantum computation promises to accelerate the solving of ce…
OpenQASM 3: A broader and deeper quantum assembly language
Andrew W. Cross, Ali Javadi-Abhari, Thomas Alexander +8
Quantum assembly languages are machine-independent languages that traditionally describe quantum computation in the circuit model. Open quantum assembly language (OpenQASM 2) was p…
Qiskit Pulse: Programming Quantum Computers Through the Cloud with Pulses
Thomas Alexander, Naoki Kanazawa, Daniel J. Egger +4
The quantum circuit model is an abstraction that hides the underlying physical implementation of gates and measurements on a quantum computer. For precise control of real quantum h…
Qiskit Backend Specifications for OpenQASM and OpenPulse Experiments
David C. McKay, Thomas Alexander, Luciano Bello +17
As interest in quantum computing grows, there is a pressing need for standardized API's so that algorithm designers, circuit designers, and physicists can be provided a common refe…
