U.S. Quantum Information Science Centers Already Producing Research Results
Quantum material’s subtle spin behavior proves theoretical predictions Spin chains in a quantum system undergo a collective twisting motion as the result of quasiparticles clustering together. Demonstrating this KPZ dynamics concept are pairs of neighboring spins, shown in red, pointing upward in contrast to their peers, in blue, which alternate directions.

Quantum Processes, Your Brain, and Consciousness: Does one Explain the Other?
Can science explain the mystery of consciousness? Read More… + After The Emperor’s New Mind was published, Penrose received a letter from Stuart Hameroff, professor of anaesthesiology at the University of Arizona, who also had a long interest in understanding consciousness. In the letter, Hameroff described tiny structures in the brain called microtubules, which he […]
RIKEN RQC-Fujitsu Collaboration Center Opens, Aims to Bring Superconducting Quantum Computers to Forefront
RIKEN, Fujitsu Launch Collaborative R&D Center in Japan in First Step Toward Realization of Superconducting Quantum Computers RIKEN and Fujitsu today announced the opening of the “RIKEN RQC-Fujitsu Collaboration Center” to promote joint research and development of foundational technologies to put superconducting quantum computers into practical use.

In Summers It’s Geraniums, This Spring at QuTech It’s Germanium for Quantum Bit Arrays in Multi-Dimensions
Semiconductor qubits scale in two dimensions The heart of any computer, its central processing unit, is built using semiconductor technology, which is capable of putting billions of transistors onto a single chip. Now, researchers from the group of Menno Veldhorst at QuTech, a collaboration between TU Delft and TNO, have shown that this technology can […]
Intel’s Quantum Cryogenics Where Cryoprober Size Matters and Silicon Wafers are the Size of Dinner Plates
Intel’s Cryoprober for Quantum Research is Unlike Any Other Tool In the world of exotic high-tech tools — they can be as big as school buses and cost millions of dollars — one that sits in a lab at Intel’s Ronler Acres campus in Oregon is truly unique. It’s called a quantum cryoprober. And no […]
Bavaria’s LRZ Quantum Integration Centre (QIC) Takes Aboard Atos’ QLM
Atos supports the Leibniz Supercomputing Centre in pioneering quantum-accelerated computing with the Atos QLM Atos […] announced that it has delivered its Atos Quantum Learning Machine (Atos QLM), the world’s highest-performing commercially available quantum simulator, to the Leibniz Supercomputing Centre (LRZ), of the Bavarian Academy of Sciences and Humanities. The Atos QLM is installed in the recently opened […]
U.S. DoD Funded Machine Learning Enabling Photonic Quantum System Corrections of Battlefield Quantum Technologies
Machine learning shows potential to enhance quantum information transfer RESEARCH TRIANGLE PARK, N.C. – Army-funded researchers demonstrated a machine learning approach that corrects quantum information in systems composed of photons, improving the outlook for deploying quantum sensing and quantum communications technologies on the battlefield. When photons are used as the carriers of quantum information to […]
China: Molecular Qubit Performs 145,000 Operations in 1.4ms
Molecular qubits stick around for longer Read More… + Researchers in China have shown that the spin of a molecular quantum bit (qubit) can remain coherent for more than 1 millisecond – long enough to perform 145 000 basic logic operations. This number, known as the qubit “figure of merit”, is 40 times higher than […]
Avoiding Postselection in Quantum Measurements
A protocol to explore entanglement dynamics via spacetime duality Read More… + Researchers at Stanford University have recently carried out a study exploring the role of quantum measurements in many-body dynamics. In their paper, published in Physical Review Letters, they specifically presented a protocol that can be used to realize dynamics that include quantum measurements […]
TU Delft: Retraction Nature Article Quantized Majorana Conductance
Retraction Nature article Quantized Majorana conductance The authors of the 2018 article Quantized Majorana conductance have retracted this article. The authors were alerted to problems by two scientists in the same research area and then went on to re-examine their earlier measurements. In doing so, they found that the main conclusion had not been adequately substantiated. As […]
