DRDO achieves milestone in quantum technology Read More… + The trials were conducted at Defence Research and Development Laboratory (DRDL) and Research Centre Imarat (RCI) at Hyderabad under realistic conditions. QKD is a secure communication method that uses cryptographic protocol involving components of quantum mechanics. Developed by Bengaluru-based Centre for Artificial Intelligence and Robotics (CAIR) […]
Quantum Technologies Push the Limits of Brain Medical Technology
New spin-out company signals quantum leap for brain imaging A new type of wearable brain scanner, designed to allow people to move freely whilst being scanned, is a step closer to being used in hospitals with the launch of a new partnership. The University of Nottingham has partnered with Kent based company Magnetic Shields Limited […]
Major Obstacle to Scaling Quantum Hardware is Cabling and Intel Has the Remedy
Intel’s latest quantum control chip manipulates qubits with radio pulses Read More… + The issue Intel sees is that as quantum computers grow more powerful and the number of qubits they contain increases, the number of cables necessary to link the qubits to the control electronics will have to increase in lockstep. Past a certain […]
New Photon Mapping Tool Shows Promise for Quantum Computing and Other Quantum Applications
Mapping quantum structures with light to unlock their capabilities Quantum combs illuminated: Upon light excitation (red and yellow beams), electrons are discovered to form comb-like wave patterns. The narrow width of the comb lines enables detecting (illuminated peaks) super-resolution images of quantum-material properties – much sharper than earlier efforts.

Qubit Readouts and Multigate Pulsing, Two New Features From Intel’s Horse Ridge II
Intel Debuts 2nd-Gen Horse Ridge Cryogenic Quantum Control Chip Horse Ridge II, Intel’s second-generation cryogenic control chip, brings key control functions for quantum computer operation into the cryogenic refrigerator — as close as possible to the qubits themselves — to streamline the complexity of control wiring for quantum systems. (Credit: Intel Corporation) What’s New: At an […]
Thanks, India! Quantum Internet Closer to Being Reality
Indian-led research team brings quantum internet closer to reality Key points… + It sounds like something straight out of spy fiction. When someone breaks into a transmission and tries to intercept it — the message is destroyed. That’s the quantum internet, which builds on the laws governing quantum mechanics, with the promise of “unhackable” transmissions. […]
Finding the Q-Spot: Ozzies Claim to Have Done So on the Road to Silicon Quantum Computing
Hitting the quantum ‘sweet spot’: researchers find best position for atom qubits in silicon Australian researchers have found the ideal position for qubits in silicon – a development that will help them to scale up atom-based quantum computers.

If Your Quantum Computer is Imperfect, Try a Classical System to Simulate It
Imperfections Lower the Simulation Cost of Quantum Computers Read More… + With a few quantum bits, an ideal quantum computer can process vast amounts of information in a coordinated way, making it significantly more powerful than a classical counterpart. This predicted power increase will be great for users but is bad for physicists trying to […]
Specialty Microelectronics Firm to Produce Components for U.S. Space Force Quantum Communications
Spotlight: SkyWater aims to boost, secure semiconductor production Points to note… + SkyWater Technology’s new 60,000-square-foot expansion — which will produce specialty microelectronics for customers ranging from medical device makers to the U.S. Space Force — embodies the push to boost domestic semiconductor production and the public-private partnerships company leaders and government officials say are […]
Method to 3D-Print Superconducting Quantum Interferometry Devices in Minutes Developed
Leiden Physicists invent printable superconducting devices + Fabricating superconducting devices on a computer chip is a multi-step and demanding procedure, requiring dedicated facilities’, says Kaveh Lahabi, a physicist at Leiden Universty,’It usually takes days to complete’. Lahabi and co-authors have developed a new approach, in which Josephson junctions, essential parts of SQUIDS, can be printed […]
