Planar fault-tolerant logical measurements with low qubit overhead
Yingli Yang, Guo Zhang, Ying Li
Fault-tolerant quantum computation critically depends on architectures uniting high encoding rates with physical implementability. Quantum low-density parity-check (qLDPC) codes, i…
Accelerating Fault-Tolerant Quantum Computation with Good qLDPC Codes
Guo Zhang, Yuanye Zhu, Ying Li
We propose a fault-tolerant quantum computation scheme that is broadly applicable to quantum low-density parity-check (qLDPC) codes. The scheme achieves constant qubit overhead and…
Constant-Overhead Magic State Injection into qLDPC Codes with Error Independence Guarantees
Guo Zhang, Yuanye Zhu, Xiao Yuan +1
Magic states are essential yet resource-intensive components for realizing universal fault-tolerant quantum computation. Preparing magic states within emerging quantum low-density…
Time-Efficient Logical Operations on Quantum Low-Density Parity Check Codes
Guo Zhang, Ying Li
We propose schemes capable of measuring an arbitrary set of commutative logical Pauli operators in time independent of the number of operators. The only condition is commutativity,…
