Zvuči nelogično, ali radi: Naučnici pronašli najčudniji način da hlade kvantne računare
Jedan od najvećih problema kvantnih računara je toplota. Čak i minimalna vibracija ili energetski poremećaj može da uništi informacije koje kvantni bitovi, takozvani kubiti, pokušavaju da obrade. Sada su istraživači sa Chalmers University of Technology pronašli način da taj problem ublaže na potpuno neočekivan način, koristeći kontrolisani šum.
TL;DR
- Quantum computers are susceptible to heat, which can destroy information processed by qubits.
- Researchers at Chalmers University of Technology developed a "quantum refrigerator" using controlled microwave noise.
- The system directs heat flow within a superconducting circuit, acting as a cooling switch.
- This is a practical confirmation of the theoretical concept of Brownian cooling.
- The quantum refrigerator can also function as a heat engine or signal amplifier.
- This could enable quantum chips to self-manage energy dissipation.
