Realizing the potential of quantum computing will require achieving sufficiently low logical
error rates. Many applications call for error rates in the $10^{-15} $ regime, but state-of-the …

As quantum circuits become more integrated and complex, additional error sources that
were previously insignificant start to emerge. Consequently, the fidelity of quantum gates …

Weak measurements of a superconducting qubit produce noisy voltage signals that are
weakly correlated with the qubit state. To recover individual quantum trajectories from these …

The Zeno effect occurs in quantum systems when a very strong measurement is applied,
which can alter the dynamics in non-trivial ways. Despite being dissipative, the dynamics …

Reconstructing the Hamiltonian of a quantum system is an essential task for characterizing
and certifying quantum processors and simulators. Existing techniques either rely on …

We theoretically and experimentally study the precision of a quantum clock near zero
temperature, explicitly accounting for the effect of continuous measurement. The clock is …

We experimentally study quantum Zeno effects in a parity-time (PT) symmetric cold atom gas
periodically coupled to a reservoir. Based on the state-of-the-art control of inter-site …

The Zeno effect, in which repeated observation freezes the dynamics of a quantum system,
stands as an iconic oddity of quantum mechanics. When a measurement is unable to …

We investigate the Landau-Zener-Stückelberg-Majorana interferometry of a
superconducting qubit in a semi-infinite transmission line terminated by a mirror. The …

We propose a reliable scheme to recover the conventional photon blockade effect in the
dispersive Jaynes-Cummings model, which describes a two-level atom coupled to a single …
