Unimon: A New Qubit to Boost Quantum Computers for Useful Applications
A group of scientists from IQM Quantum Computers, Aalto University, and VTT Technical Research Centre of Finland have discovered a new superconducting qubit, the unimon, to increase the accuracy of quantum computations. The team has achieved the first quantum logic gates with unimons at 99.9% fidelity — a major milestone on the quest to build commercially useful quantum computers.
It’s Out! New Theory and Calculations to Predict Spin Decoherence in Materials With High Accuracy
Marco Bernardi, professor of applied physics, physics and materials science; and Jinsoo Park (MS ’20, PhD ’22), postdoctoral scholar research associate in applied physics and materials science, have developed a new theory and numerical calculations to predict spin decoherence in materials with high accuracy.
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.
