(Phys.org) Professor Michelle Simmons’ team at UNSW Sydney has demonstrated a compact sensor for accessing information stored in the electrons of individual atoms—a breakthrough that brings us one step closer to scalable quantum computing in silicon. The research was conducted within the Simmons group at the Centre of Excellence for Quantum Computation and Communication Technology (CQC2T). “This represents a major advance in how we read information embedded in our qubits,” concludes Simmons. “The result confirms that single-gate reading of qubits is now reaching the sensitivity needed to perform the necessary quantum error correction for a scalable quantum computer.”
Quantum bits (or qubits) made from electrons hosted on single atom in semiconductors is a promising platform for large-scale quantum computers.
