Equal1, a company focused on silicon-powered quantum computing, announced advances in its quantum technology, showcasing performance improvements in silicon qubit arrays and introducing a new quantum controller chip. The developments aim to support scalable quantum computing using existing silicon infrastructure, according to a company blog post. The company reported achieving the following metrics on a six-qubit array fabricated using a silicon-germanium CMOS-compatible process:
1. Single-qubit gate fidelity of 99.4% with a gate speed of 84 nanoseconds.
2. Two-qubit gate fidelity of 98.4% with a gate speed of 72 nanoseconds.
These results are positioned as a step toward full-scale, error-corrected quantum processors that can be produced by conventional silicon foundries. Elena Blokhina, Equal1’s Chief Scientific Officer said: “Today marks a critical inflection point for Equal1 and the quantum computing industry. Equal1 has always believed that silicon is the vehicle to scale quantum computers and today, with these world leading qubit and control chip results, we have taken a major step towards this vision.” Nodar Samkharadze, Equal1’s Chief Quantum Architect said: “This result demonstrates the massive benefit of silicon qubits – the ability to achieve the performance required for scaling in two key areas – fidelity and speed of quantum
