Tight Lower Bounds for State Tomography with Limited Entanglement
Ufuk Keskin, Jason Luo, Mahbod Majid +1
We study state tomography when each measurement acts on at most fresh copies and no quantum memory is retained between blocks. We prove a lower bound matching the upper bound i…
Quantum Chinese Remainder Clock
Ivri Nagar, Alioscia Hamma, Mikel Palmero +3
The Chinese remainder theorem is used in metrology for extending the range of quantum clocks/radar/interferometry, where the phase of a signal is known relative to a set of oscilla…
Butterfly Echo Protocol for Axis-Agnostic Heisenberg-Limited Metrology
Jacob Bringewatt, Leon Zaporski, Matthew Radzihovsky +4
The extreme sensitivity of chaotic systems to external perturbations makes them natural candidates for sensing applications. We propose a single-shot echo-based protocol for estima…
