Rapid readout of a register of qubits using open loop quantum control
Joshua Combes, Aaron Denney, Howard M. Wiseman
Measurements are a primitive for characterizing quantum systems. Reducing the time taken to perform a measurement may be beneficial in many areas of quantum information processing.…
Classical correlation alone supplies the anomaly to weak values
Christopher Ferrie, Joshua Combes
The question of what is genuinely quantum about weak values is only ever going to elicit strongly subjective opinions---it is not a scientific question. Good questions, when compar…
Weak-value amplification: state of play
George C. Knee, Joshua Combes, Christopher Ferrie +1
Weak values arise in quantum theory when the result of a weak measurement is conditioned on a subsequent strong measurement. The majority of the trials are discarded, leaving only…
In-situ characterization of quantum devices with error correction
Joshua Combes, Christopher Ferrie, Chris Cesare +4
Syndrome measurements made in quantum error correction contain more information than is typically used. We show that the statistics of data from syndrome measurements can be used t…
Non-absorbing high-efficiency counter for itinerant microwave photons
Bixuan Fan, Göran Johansson, Joshua Combes +2
Detecting an itinerant microwave photon with high efficiency is an outstanding problem in microwave photonics and its applications. We present a scheme to detect an itinerant micro…
How the result of a single coin toss can turn out to be 100 heads
Christopher Ferrie, Joshua Combes
We show that the phenomenon of anomalous weak values is not limited to quantum theory. In particular, we show that the same features occur in a simple model of a coin subject to a…
