Tiny Cryogenic Device Could Transform Quantum Computing
Scientists have built a new cryogenic device that could make quantum computers cheaper, more practical, and easier to scale.
Quantum computers need to work at temperatures close to absolute zero (−273°C), because their “qubits” — the basic building blocks of quantum systems — are extremely delicate. To function, they require special amplifiers that boost the weak signals qubits give off. But these amplifiers usually generate a lot of heat, making cooling systems expensive and bulky.
A Canadian startup, Qubic Technologies, has created a new type of amplifier called a cryogenic traveling-wave parametric amplifier (TWPA). Made from special “quantum materials,” it produces almost no heat at all — cutting thermal output 10,000 times lower than existing solutions.
This breakthrough means quantum computers could one day be more affordable and reliable, bringing them closer to real-world commercial use. Qubic plans to launch the new device in 2026.
As CEO Jérôme Bourassa explained, quantum computing is moving fast, but heat and energy issues are still major obstacles. This innovation could remove one of the biggest barriers to building practical, large-scale quantum machines.
