The closer a quantum circuit is to what’s known as a pseudorandom unitary design, the more it mimics the behavior of a perfectly random quantum process.

Non-unitary dynamics Many-body non-unitary dynamics can drive the system to non-thermal steady states which are hard to realize in the unitary dynamics. Measurement driven entanglement phase ...

This experiment shows that the combination of a single-qubit and two-qubit gate can simulate all possible unitary operations. This means that we can create a universally programmable quantum ...
