Accelerating Progress Towards Practical Quantum Advantage: The Quantum Technology Demonstration Project Roadmap
Paul Alsing, Phil Battle, Joshua C. Bienfang +32
Quantum information science and technology (QIST) is a critical and emerging technology with the potential for enormous world impact and is currently invested in by over 40 nations…
Qubit Geodesics on the Bloch Sphere from Optimal-Speed Hamiltonian Evolutions
Carlo Cafaro, Paul M. Alsing
In the geometry of quantum evolutions, a geodesic path is viewed as a path of minimal statistical length connecting two pure quantum states along which the maximal number of statis…
Unconditional remote entanglement using second-harmonic generation and twin two-mode squeezed vacuum states
Richard J. Birrittella, James Schneeloch, Christopher C. Tison +3
We propose a photonics-based, continuous-variable (CV) form of remote entanglement utilizing strictly second-order nonlinear optical interactions that does not require the implemen…
Enhanced Hong-Ou-Mandel Manifolds and figures of merit for linear chains of identical micro-ring resonators
Peter L. Kaulfuss, Paul M. Alsing, A. Matthew Smith +2
We present an exact analytic expression for the Hong-Ou-Mandel (HOM) curve for any number of identical Micro-Ring Resonators (MRRs) in a linear chain. We investigate the extreme st…
Complexity of Pure and Mixed Qubit Geodesic Paths on Curved Manifolds
Carlo Cafaro, Paul M. Alsing
It is known that mixed quantum states are highly entropic states of imperfect knowledge (i.e., incomplete information) about a quantum system, while pure quantum states are states…
A Differential-Geometric Approach to Quantum Ignorance Consistent with Entropic Properties of Statistical Mechanics
Shannon Ray, Paul M. Alsing, Carlo Cafaro +1
In this paper, we construct the metric tensor and volume for the manifold of purifications associated with an arbitrary reduced density operator . We also define a quantum coa…
