Quantum Lego Power-up: Designing Transversal Gates with Tensor Networks
ChunJun Cao, Brad Lackey
Transversal gates are the simplest form of fault-tolerant gates and are relatively easy to implement in practice. Yet designing codes that support useful transversal operations --…

Quantum Public Key Encryption for NISQ Devices
Nishant Rodrigues, Walter O. Krawec, Brad Lackey +2
Quantum public-key encryption (PKE), where public-keys and/or ciphertexts can be quantum states, is an important primitive in quantum cryptography. Unlike classical PKE (e.g., RSA…

Quantum Circuit Tensors and Enumerators with Applications to Quantum Fault Tolerance
Alon Kukliansky, Brad Lackey
We extend the recently introduced notion of tensor enumerator to the circuit enumerator. We provide a mathematical framework that offers a novel method for analyzing circuits and e…
