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…
Quantum Position Verification with Remote Untrusted Devices
Gautam A. Kavuri, Yanbao Zhang, Abigail R. Gookin +17
Position information underpins many modern technologies, from navigation and timing to authentication and critical infrastructure. However, classical methods of proving that inform…
Constructing an approximate logical Markovian model of consecutive QEC cycles of a stabilizer code
Alex Kwiatkowski, Aaron J. Friedman, Shawn Geller +3
As quantum error correction (QEC) experiments continue to make rapid progress, there is increased interest in designing experiments with guarantees of logical performance. At prese…
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…
