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, : +256
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…
