Quantum applications based on density matrix vectorization: a polynomial-time quantum algorithm for some hard ground state problems and an unconditionally decoherence-free quantum error mitigation method
Abstract: In this talk, we will give two quantum applications based on density matrix vectorization. Vectorizing density matrices has been a useful mathematical trick for simplifying many concepts in...
