Negativity vs. Purity and Entropy in Witnessing Entanglement
James Schneeloch, H Shelton Jacinto, Christopher C. Tison +1
In this work, we show that while all measures of mixedness may be used to witness entanglement, all such entangled states must have a negative partial transpose (NPT). Though compu…
Fundamentals In Quantum Algorithms: A Tutorial Series Using Qiskit Continued
Daniel Koch, Saahil Patel, Laura Wessing +1
With the increasing rise of publicly available high level quantum computing languages, the field of Quantum Computing has reached an important milestone of separation of software f…
The Parity Operator: applications in quantum metrology
Richard J. Birrittella, Paul M. Alsing, Christopher C. Gerry
In this paper, we review the use of parity as a detection observable in quantum metrology as well as introduce some original findings with regards to measurement resolution in Rams…
A direct interferometric test of the nonlinear phase shift gate
Peter L. Kaulfuss, Paul M. Alsing, Edwin E. Hach +3
We propose a direct interferometric test of the Non-Linear Phase Shift Gate (NLPSG), an essential piece of a Knill Laflamme Milburn Contolled-NOT (KLM CNOT) gate. We develop our an…
Geometric aspects of analog quantum search evolutions
Carlo Cafaro, Shannon Ray, Paul M. Alsing
We use geometric concepts originally proposed by Anandan and Aharonov to show that the Farhi-Gutmann time optimal analog quantum search evolution between two orthogonal quantum sta…
Information Geometric Aspects of Probability Paths with Minimum Entropy Production for Quantum State Evolution
Steven Gassner, Carlo Cafaro, Sean A. Ali +1
We present an information geometric analysis of both entropic speeds and entropy production rates arising from geodesic evolution on manifolds parametrized by pure quantum states.…
