Observable and computable entanglement in time
Alexey Milekhin, Zofia Adamska, John Preskill
We propose a novel family of entanglement measures for time-separated subsystems. Our definitions are applicable to any quantum system, continuous or discrete. To illustrate their…

Observable-projected ensembles
Alexey Milekhin, Sara Murciano
Measurements in many-body quantum systems can generate non-trivial phenomena, such as preparation of long-range entangled states, dynamical phase transitions, or measurement-altere…

From black hole interior to quantum complexity through operator rank
Alexey Milekhin
It has been conjectured that the size of the black hole interior captures the quantum gate complexity of the underlying boundary evolution. In this short note we aim to provide a f…
