Leggett-Garg inequality with a kicked quantum pump
Andrew N. Jordan, Alexander N. Korotkov, Markus Buttiker
A kicked quantum nondemolition measurement is introduced, where a qubit is weakly measured by pumping current. Measurement statistics are derived for weak measurements combined wit…
Continuous quantum measurement with independent detector cross-correlations
Andrew N. Jordan, Markus Buttiker
We investigate the advantages of using two independent, linear detectors for continuous quantum measurement. For single-shot quantum measurement, the measurement is maximally effic…
Mesoscopic threshold detectors: Telegraphing the size of a fluctuation
Andrew N. Jordan, Eugene V. Sukhorukov
We propose a two-terminal method to measure shot noise in mesoscopic systems based on an instability in the current-voltage characteristic of an on-chip detector. The microscopic n…
Ground State Entanglement Energetics
M. Buttiker, A. N. Jordan
We consider the ground state of simple quantum systems coupled to an environment. In general the system is entangled with its environment. As a consequence, even at zero temperatur…
Entanglement Energetics in the Ground State
Andrew N. Jordan, Markus Buttiker
We show how many-body ground state entanglement information may be extracted from sub-system energy measurements at zero temperature. A precise relation between entanglement and en…
