Some measurements in quantum mechanics disturb each other. This has puzzled physicists
since the formulation of the theory, but only in recent decades has the incompatibility of …

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 …

Macroscopic realism is the name for a class of modifications to quantum theory that allow
macroscopic objects to be described in a measurement-independent manner, while largely …

We present a new characterization of quantum theory in terms of simple physical principles
that is different from previous ones in two important respects: first, it only refers to properties …

We realize indirect partial measurement of a transmon qubit in circuit quantum
electrodynamics by interaction with an ancilla qubit and projective ancilla measurement with …

We show that the quantum bound for temporal correlations in a Leggett-Garg test,
analogous to the Tsirelson bound for spatial correlations in a Bell test, strongly depends on …

The study of individual quantum systems in solids, for use as quantum bits (qubits) and
probes of decoherence, requires protocols for their initialization, unitary manipulation, and …

Tests of local realism and macrorealism have historically been discussed in very similar
terms: Leggett-Garg inequalities follow Bell inequalities as necessary conditions for classical …

In the past 50 years, quantum physicists have discovered, and experimentally demonstrated,
a phenomenon which they termed superoscillations. Aharonov and his collaborators …

Deep-level defects are usually considered undesirable in semiconductors as they typically
interfere with the performance of present-day electronic and optoelectronic devices …
