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…
Topological Mixed States: Phases of Matter from Axiomatic Approaches
Tai-Hsuan Yang, Bowen Shi, Jong Yeon Lee
For closed quantum systems, topological orders are understood through the equivalence classes of ground states of gapped local Hamiltonians. The generalization of this conceptual p…
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…
