Benchmarking exchange-only control of a 48-spin singlet manifold
HRL Quantum Team, Microsoft Collaborators, : +125
Exchange-only quantum computing benefits from high fidelity and straightforward control afforded by the exchange interaction. However, independently controllable qubits must be enc…
Spin singlets are useful
Silas Hoffman, Edward H. Chen, Matthew Brooks +6
We evaluate the utility of the spin-zero manifold of an exchange-coupled array of spins for tasks in quantum computation and quantum simulation. Since pairs of electrons can be…
A digitally controlled silicon quantum processing unit
Members of the HRL Quantum Team, Collaborators, : +255
Commercially-relevant quantum computers will require large numbers of high-performing qubits that can be manufactured, integrated, and controlled at scale. Silicon exchange-only (E…
Quantum Benchmarking via Random Dynamical Quantum Maps
Daniel Volya, Prabhat Mishra
We present a benchmarking protocol for universal quantum computers, achieved through the simulation of random dynamical quantum maps. This protocol provides a holistic assessment o…
Fast Quantum Process Tomography via Riemannian Gradient Descent
Daniel Volya, Andrey Nikitin, Prabhat Mishra
Constrained optimization plays a crucial role in the fields of quantum physics and quantum information science and becomes especially challenging for high-dimensional complex struc…
QudCom: Towards Quantum Compilation for Qudit Systems
Daniel Volya, Prabhat Mishra
Qudit-based quantum computation offers unique advantages over qubit-based systems in terms of noise mitigation capabilities as well as algorithmic complexity improvements. However,…
quAssert: Automatic Generation of Quantum Assertions
Hasini Witharana, Daniel Volya, Prabhat Mishra
Functional validation is necessary to detect any errors during quantum computation. There are promising avenues to debug quantum circuits using runtime assertions. However, the exi…
State Preparation on Quantum Computers via Quantum Steering
Daniel Volya, Prabhat Mishra
One of the major components for realizing quantum computers is the ability to initialize the computer to a known fiducial state, also known as state preparation. We demonstrate a s…
