#4154 Desktop Quantum Computers #4154 Describe a desktop quantum computing solution where super-cooling and error correction are no long an issue The quest for a "room-temperature, error-free" desktop quantum computer moves us away from superconducting qubits (which require dilution refrigerators) and toward architectures that leverage the inherent stability of atomic or topological systems. In this scenario, we are describing a Photonic Topological Quantum Computer . 1. The Hardware: Ambient Temperature Operation Instead of using matter-based qubits that succumb to thermal noise, this system uses photons as the information carriers. Silicon Photonics: The processor is a CMOS-compatible silicon chip. Since photons do not interact with their environment easily, they don't require the near-absolute zero temperatures ( 20 mK ) required by IBM or Google’s systems. Nanoscale Waveguides: Instead of wires, the "circuits" are etched channels that guide laser light. ...
