Quantum theory predicts the existence of genuinely tripartite-entangled states, which cannot
be obtained from local operations over any bipartite-entangled states and unlimited shared …

We present a universal mechanism that, acting on any target qubit, propagates it to the state
it had T time units before the experiment started. This protocol works by setting the target on …

The challenging requirements of large scale quantum information processing using
parametric heralded single photon sources involve maximizing the interference visibility …

In quantum mechanics, the unitary nature of time evolution makes it intrinsically reversible,
given control over the system in question. Remarkably, there have been several recent …

The physical process in the macroscopic world unfolds along a single time direction, while
the evolution of a quantum system is reversible in principle. How to recover a quantum …

Quantum resetting protocols allow a quantum system to be sent to a state in the past by
making it interact with quantum probes when neither the free evolution of the system nor the …

Undoing a unitary operation, ie, reversing its action, is the task of canceling the effects of a
unitary evolution on a quantum system, and it may be easily achieved when the unitary is …

This thesis studies three new non-relativistic quantum effects related to space and time. First,
we determine that quantum theory with complex numbers predicts experimental results …
