Journal of Operator Theory, Vol. 64, No. 2 (Fall 2010), pp. 265-298 (34 pages) We prove some noncommutative analogues of a theorem proved by Plotkin and Rudin about isometries between subspaces of ...

We study the following question: suppose that A and ℬ are two algebras of complex n × n matrices such that the ring commutator [A, B] = AB – BA is "small" for each A ∈ A and B ∈ ℬ; does this imply ...

This study demonstrates how integrating decoherence-free subspaces with dynamical decoupling enhances quantum state fidelity, offering a practical route to more noise-resilient quantum computing ...

Device-independent method certifies genuinely entangled subspaces in photonic and superconducting systems by University of Science and Technology of China edited by Gaby Clark, reviewed by Robert Egan ...

In a study published in Reports on Progress in Physics, research teams led by Academician GUO Guangcan and Prof. LIU Biheng from the University of Science and Technology of China (USTC) of the Chinese ...
