Two Routes to Fewer Qubits: How qLDPC Codes and Erasure Qubits Attack Quantum Computing's Overhead Problem

Fault-tolerant quantum computing faces a significant overhead problem, requiring vast numbers of physical qubits for each logical qubit. Two promising strategies, qLDPC codes and erasure qubits, offer distinct paths to reduce this physical-to-logical qubit ratio and advance quantum computing.
