Dilution Refrigerator

Recent advances point the way to useful classical-quantum hybrids

Quantum computers promise to solve challenging tasks in material science and cryptography that will remain out of reach even for the most powerful conventional supercomputers in the future. Yet, this will likely require millions of high-quality qubits due to the required error correction.

Project Goldeneye lays the groundwork for the quantum industry's ability to scale up the next generation of low-temperature refrigeration.

Despite intense competition from savvy startups and techno giants, Lego could enter the race to build a quantum computer.

Approximately two decades ago, it was shown theoretically that quantum computers could easily solve certain computationally demanding problems like factoring large numbers into prime numbers or searching efficiently in databases. These possibilities have triggered intense experimental efforts towards the physical realization of scalable quantum processors (such that it would be possible to increase the size of…

If you've ever tried to carry on a conversation in a noisy room, you'll be able to relate to the scientists and engineers trying to "hear" the signals from experimental quantum computing devices called qubits. These basic units of quantum computers are early in their development and remain temperamental, subject to all manner of interference. Stray "noise" can masquerade as a functioning qubit or even render it…

Australian scientists are making strides towards solving one of the greatest mysteries of the universe: the nature of invisible "dark matter."

Scientists have developed a qubit platform formed by freezing neon gas into a solid, spraying electrons from a light bulb's filament onto it, and trapping a single electron there. This system shows great promise as an ideal building block for quantum computers.

MIT physicists have observed fractional quantum Hall effect in simple pentalayer graphene. The finding could make it easier to develop more robust quantum computers.

Scientists are trying to master the basic computing element known as a qubit to make quantum computers more powerful than electronic machines

The long-term vision for quantum computing is the ability to leverage millions of noise-free qubits to address selected problems that are hard to solve with classical computers. Application fields that may benefit from this technology include materials synthesis, pharmaceutical drug development, and cybersecurity, to name a few.

Welcome to the future. It's 2022 and the near billion-dollar quantum computing sector has gone from a passion project for forward-thinking physicists to a thriving B2B industry. Experts ...

Bose-Einstein condensate of excitons is expected in photo-excited bulk semiconductors, but a direct experimental evidence has been lacking. Here the authors report the observation of a condensate of 1s paraexcitons in Cu2O using real-space mid-infrared absorption imaging realized in a dilution refrigerator.

Scientists have created a Bose-Einstein condensate out of excitons — quasiparticles that combine electrons and positively charged "holes" — in a semiconductor. Quasiparticle Bose-Einstein condensates have for six decades been something of a holy grail of low-temperature physics.

MIT PhD student Alex Greene studies superconducting quantum computing systems, working to reduce errors that limit the length and complexity of the "programs" the computers can run.

A new qubit platform could transform quantum information science and technology. You are no doubt viewing this article on a digital device whose basic unit of information is the bit, either 0 or 1. Scientists around the world are racing to develop a new type of computer based on the use of quantum

A collaboration between computer scientists and physicists at the University of Chicago broke through one of the key obstacles for large-scale quantum computing by figuring out how to move their control signals "inside the fridge."

Microsoft and Nokia are developing a contentious new type of quantum computer

NASA's Wallops Flight Facility in Virginia manages the agency's scientific balloon flight program with 10 to 15 flights each year from launch sites
