Aalto University Pioneers Qubit Measurement Beyond Heisenberg Uncertainty
Researchers achieve breakthrough in quantum computing by using thermal bolometers for high-fidelity qubit readouts, significantly reducing quantum noise.
- Aalto University's Quantum Computing and Devices group successfully measures qubits with thermal bolometers, evading the Heisenberg uncertainty principle.
- This new method offers a more accurate, single-shot readout of qubits, achieving up to 92.7% fidelity after adjusting for energy relaxation.
- Bolometers used are 100 times smaller than traditional amplifiers, facilitating easier integration into quantum computers.
- Future enhancements could push bolometer fidelity to 99.9% within 200 nanoseconds, leveraging materials like graphene.
- The research, funded by several European grants, underscores significant advancements in quantum measurement technology.
