Quantified convergence of general homodyne measurements with applications to continuous variable quantum computing
Emanuel Knill, Ezad Shojaee, James R. van Meter +2
In arXiv:2503.00188 we introduced broadband pulsed (BBP) homodyne measurements as a generalization of standard pulsed homodyne quadrature measurements. BBP can take advantage of de…
Broadband pulsed quadrature measurements with calorimeters
Ezad Shojaee, James R. van Meter, Karl Mayer +2
A general one-dimensional quantum optical mode is described by a shape in the time or frequency domain. A fundamental problem is to measure a quadrature operator of such a mode. If…
Constraints on Gaussian Error Channels and Measurements for Quantum Communication
Alex Kwiatkowski, Ezad Shojaee, Sristy Agrawal +4
Joint Gaussian measurements of two quantum systems can be used for quantum communication between remote parties, as in teleportation or entanglement swapping protocols. Many types…
Filter functions for the Glauber-Sudarshan -function regularization
Mani Zartab, Ezad Shojaee, Saleh Rahimi-Keshari
The phase-space quasi-probability distribution formalism for representing quantum states provides practical tools for various applications in quantum optics such as identifying the…
Entanglement Thresholds of Doubly-Parametric Quantum Transducers
Curtis L. Rau, Akira Kyle, Alex Kwiatkowski +4
Doubly-parametric quantum transducers, such as electro-opto-mechanical devices, are quickly approaching quantum operation as decoherence mechanisms such as thermal noise, loss, and…
Direct observation of deterministic macroscopic entanglement
Shlomi Kotler, Gabriel A. Peterson, Ezad Shojaee +9
Quantum entanglement of mechanical systems emerges when distinct objects move with such a high degree of correlation that they can no longer be described separately. Although quant…
Squeezing the angular momentum of an ensemble of complex multi-level atoms
Daniel Hemmer, Enrique Montano, Ben Q. Baragiola +4
Squeezing of collective atomic spins has been shown to improve the sensitivity of atomic clocks and magnetometers to levels significantly below the standard quantum limit. In most…
Optimal Pure-State Qubit Tomography via Sequential Weak Measurements
Ezad Shojaee, Christopher S. Jackson, Carlos A. Riofrio +2
The spin-coherent-state positive-operator-valued-measure (POVM) is a fundamental measurement in quantum science, with applications including tomography, metrology, teleportation, b…
