Flagging the Clifford hierarchy:~Fault-tolerant logical rotations via measuring circuit gauge operators of non-Cliffords
Shival Dasu, Ben Criger
We provide a recursively defined sequence of flag circuits which will detect logical errors induced by non-fault-tolerant gates on CSS codes with a…
Computing with many encoded logical qubits beyond break-even
Shival Dasu, Matthew DeCross, Andrew Y. Guo +42
High-rate quantum error correcting (QEC) codes encode many logical qubits in a given number of physical qubits, making them promising candidates for quantum computation. Implementi…
A Classification of Transversal Clifford Gates for Qubit Stabilizer Codes
Shival Dasu, Simon Burton
This work classifies stabilizer codes by the set of diagonal Clifford gates that can be implemented transversally on them. We show that, for any stabilizer code, its group of diago…
Breaking even with magic: demonstration of a high-fidelity logical non-Clifford gate
Shival Dasu, Simon Burton, Karl Mayer +7
Encoding quantum information to protect it from errors is essential for performing large-scale quantum computations. Performing a universal set of quantum gates on encoded states d…
Order-of-magnitude extension of qubit lifetimes with a decoherence-free subspace quantum error correction code
Shival Dasu, Ben Criger, Cameron Foltz +9
Constructing an efficient and robust quantum memory is central to the challenge of engineering feasible quantum computer architectures. Quantum error correction codes can solve thi…
