Quantum minimum description of density matrices
Patrick Hayden, Alexander Maloney, Jinzhao Wang +1
We study a variant of Schumacher compression. The task asks for the minimal memory cost for compressing many copies of a density matrix with known spectrum and unknown eigenbasis,…
Free entropy and quantum minimum description length
Patrick Hayden, Alexander Maloney, Jinzhao Wang +1
In free probability, Voiculescu's free entropy counts matrix microstates that approximate an operator. It is a non-commutative analog of the Shannon entropy, distinct from any quan…
Alpha-bit state merging
Jessica Yeh, Jinzhao Wang, Patrick Hayden
State merging is a fundamental protocol in quantum information theory that generalizes quantum teleportation. Traditionally, it is achieved by local operations on shared entangleme…
Quantum Energy Teleportation versus Information Teleportation
Jinzhao Wang, Shunyu Yao
Quantum energy teleportation (QET) is the phenomenon in which locally inaccessible energy is activated as extractable work through collaborative local operations and classical comm…
