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…
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…
Gauge color codes in two dimensions
Cody Jones, Peter Brooks, Jim Harrington
We present a family of quantum error-correcting codes that support a universal set of transversal logic gates using only local operations on a two-dimensional array of physical qub…
Numerical analysis of decoy state quantum key distribution protocols
Patrick Rice, Jim Harrington
Decoy state protocols are a useful tool for many quantum key distribution systems implemented with weak coherent pulses, allowing significantly better secret bit rates and longer m…
Localized closed timelike curves can perfectly distinguish quantum states
Todd A. Brun, Jim Harrington, Mark M. Wilde
We show that qubits traveling along closed timelike curves are a resource that a party can exploit to distinguish perfectly any set of quantum states. As a result, an adversary wit…
Practical long-distance quantum key distribution system using decoy levels
D. Rosenberg, C. G. Peterson, J. W. Harrington +9
Quantum key distribution (QKD) has the potential for widespread real-world applications. To date no secure long-distance experiment has demonstrated the truly practical operation n…
