Japan’s Advancements in Operation-Based Error Correction Significantly Reduce Effects of Burst Errors
Nippon Telegraph and Telephone Corporation (NTT), Kyushu University, and the University of Tokyo have proposed the world’s first architecture to dynamically correct errors in accordance with quantum computer operations…
Max Planck Institute of Quantum Optics Has Laid the Foundation for the Development of Future Quantum Network
A team of researchers at the MPQ has pioneered the integration of erbium atoms with special optical properties into a silicon crystal.
New Quantum Computer Architecture Could Unleash Universal Quantum Computer Power
Quantum computer power is still being stymied by numerous challenges. One such challenge is the requirement for each quantum bit to interact with all others.
Cousin of the Qubit, the Qudit, Has More: More Information, More Noise Resistance
Although the word “qudit” might look like a typo, this lesser-known cousin of the qubit, or quantum bit, can carry more information and is more resistant to noise — both of which are key qualities needed to improve the performance of quantum networks, quantum key distribution systems and, eventually, the quantum internet.
Seeing Electron Movement at Fastest Speed Ever Could Help Unlock Next-Level Quantum Computing
New technique could enable processing speeds a million to a billion times faster than today’s computers and spur progress in many-body physics.
“Quantum Bus” Could Be the Key Component to Master the Leap to Millions of Qubits
Many applications require quantum processors with millions of quantum bits. Today’s prototypes merely come up with a few of these compute units. At some point, the number of signal lines becomes a bottleneck. The lines take up too much space compared to the size of the tiny qubits. And a quantum chip cannot have millions of inputs and outputs.
Getting Quantum-Ready for Ongoing Search for Life in Space
Zapata and the University of Hull developed new techniques to extrapolate meaningful data from noisy quantum devices and used it to calculate the ro-vibrational spectrum of hydrogen to obtain results that are comparable with the state-of-the-art classical simulations, as well as the experimental results.
Usually, a Defect in a Diamond Is a Bad Thing
Usually, a defect in a diamond is a bad thing… But for engineers, miniscule blips in a diamond’s otherwise stiff crystal structure are paving the way for ultrasensitive quantum sensors that push the limits of today’s technologies.
A Thin Device Triggers One of Quantum Mechanics’ Strangest and Most Useful Phenomena
Scientists at Sandia National Laboratories and Max Planck Institute for the Science of Light have reported on a device that could replace a roomful of equipment used to entangle photons.
Promise in Establishing Measurement of Entangled Photons Down Possibly as Short as the Zeptosecond
Researchers from Purdue University have proposed a novel, unconventional approach to generate a special light source made up of entangled photons.
