Finite-round quantum error correction on symmetric quantum sensors
Yingkai Ouyang, Gavin K. Brennen
In quantum sensing using entangled probes, the variance of the estimated signal strength scales like at the Heisenberg limit, which is a quadratic improv…

Permutational-key quantum homomorphic encryption with homomorphic quantum error-correction
Yingkai Ouyang, Peter P. Rohde
The gold-standard for security in quantum cryptographic protocols is information-theoretic security. Information-theoretic security is surely future-proof, because it makes no assu…

Constructing quantum codes from any classical code and their embedding in ground space of local Hamiltonians
Ramis Movassagh, Yingkai Ouyang
Implementing robust quantum error correction (QEC) is imperative for harnessing the promise of quantum technologies. We introduce a framework that takes {\it any} classical code an…
