The performance of superconducting qubits has improved by several orders of magnitude in
the past decade. These circuits benefit from the robustness of superconductivity and the …

Superconducting circuits based on Josephson junctions exhibit macroscopic quantum
coherence and can behave like artificial atoms. Recent technological advances have made …

Since its introduction 25 years ago, the quantum weak value has gradually transitioned from
a theoretical curiosity to a practical laboratory tool. While its utility is apparent in the recent …

Remarkable progress towards realizing quantum computation has been achieved using
natural and artificial atoms as qubits. This paper presents a brief overview of the current …

The efficiency of the future devices for quantum information processing is limited mostly by
the finite decoherence rates of the individual qubits and quantum gates. Recently …

In contrast to the spatial Bell's inequalities which probe entanglement between spatially
separated systems, the Leggett–Garg inequalities test the correlations of a single system …

The act of measurement bridges the quantum and classical worlds by projecting a
superposition of possible states into a single (probabilistic) outcome. The timescale of this …

We continuously measure the state of a superconducting quantum bit coupled to a
microwave readout cavity by using a fast, ultralow-noise parametric amplifier. This …

Recent work by Lundeen et al.[Nature (London) 474, 188 (2011) NATUAS 0028-0836
10.1038/nature10120] directly measured the wave function by weakly measuring a variable …

This paper starts with a brief review of the topic of strong and weak pre-and post-selected
(PPS) quantum measurements, as well as weak values, and afterwards presents original …
