Stability of Quantum LDPC States under Local Pauli Noise
Tai-Hsuan Yang, Andrew D. Kim, Akash Vijay +1
Quantum low-density parity-check (qLDPC) codes have a canonical mixed state---the normalized projector onto the code space---that lies at the intersection of quantum error correcti…
Quantum data processing equality
Tai-Hsuan Yang
The quantum data processing inequality asserts that quantum relative entropy is monotonically non-increasing under quantum channels. Here, we promote this fundamental inequality to…
Modular commutator as a robust topological invariant and approximate Markovianity
Tai Hsuan Yang
The modular commutator provides a bulk, local, single-wave-function probe of the chiral central charge for gapped ground states. Its invariance under deformations was previou…
When can classical neural networks represent quantum states?
Tai-Hsuan Yang, Mehdi Soleimanifar, Thiago Bergamaschi +1
A naive classical representation of an n-qubit state requires specifying exponentially many amplitudes in the computational basis. Past works have demonstrated that classical neura…
