Measuring the spin of a spin-1/2 and getting a result of 7
Joseph McGowan, Nicholas Mantella, Noah Baker +1
The weak value of an operator is the average result of measuring that operator on a quantum system given specified initial and final states. The overlap between these states appear…
Experimental quantum state learning with pairs of photons
C. Pria Dobney, Johan Henaff, Allen Kasum +5
Tomography allows one to estimate the density matrix describing the state an ensemble of quantum systems are prepared in (for example, polarization tomography determines the polari…
Single Photon Cross-Phase Shifts Can Be Enhanced by Localization in both Frequency and Time
Xinyu Jiao, Vida-Michelle Nixon, Kyle Thompson +1
Single-photon optical nonlinearities face a fundamental trade-off: maximum nonlinearity requires both spectral resonance (narrow bandwidth) and high peak intensity (short duration)…
Compressing Quantum Fisher Information
Rui Jie Tang, Jeremy Guenza Marcus, Noah Lupu-Gladstein +5
We show that the quantum Fisher information about any phase parameter encoded in a family of pure quantum states can be faithfully compressed into a single qubit, accompanied by a…
Theory of direct measurement of the quantum pseudo-distribution via its characteristic function
Andrew N. Jordan, David R. M. Arvidsson-Shukur, Aephraim M. Steinberg
We propose a method for directly measuring the quantum mechanical pseudo-distribution of observable properties via its characteristic function. Vandermonde matrices of the eigenval…
Spin coherence scale: operator-ordering sensitivity beyond the Heisenberg-Weyl group
Aaron Z. Goldberg, Andre J. Rodrigues, Y. Batuhan Yilmaz +2
We introduce the spin coherence scale as a measure of quantum coherence for spin systems, generalizing the quadrature coherence scale (QCS) previously defined for quadrature observ…
