The Race Toward Quantum Advantage

Quantum computing has yet to show an advantage over conventional computing, but huge sums of money are betting it will. So far that hasn't happened. Early quantum computers were created in the mid-1990s after mathematicians had demonstrated the effectiveness of applying quantum approaches to some problems. At that stage they were simulated using conventional computing, but it started the rac... » read more

Research Bits: June 27

Tunable soliton microcomb Researchers from the University of Rochester and CalTech say they have created the first microwave-rate soliton microcomb that can control the repetition rate at a high speed. Microcombs are frequency combs that can fit on a microchip, which will be useful in photonics. Solitons are solitary waves that keep their shape as they move at a constant speed. The team put an... » read more

Max Planck Generates Up To 14 Entangled Photons In A Defined Way And With High Efficiency

A new technical paper titled "Efficient generation of entangled multiphoton graph states from a single atom" was published by researchers at Max Planck Institute of Quantum Optics. The team of physicists "generated up to 14 entangled photons in an optical resonator, which can be prepared into specific quantum physical states in a targeted and very efficient manner. The new method could facil... » read more

QubiC: An Open-Source FPGA-Based Control and Measurement System for Superconducting Quantum Information Processors

Abstract: "As quantum information processors grow in quantum bit (qubit) count and functionality, the control and measurement system becomes a limiting factor to large-scale extensibility. To tackle this challenge and keep pace with rapidly evolving classical control requirements, full control stack access is essential to system-level optimization. We design a modular field-programmable gate a... » read more

Materials and Device Simulations for Silicon Qubit Design and Optimization

Abstract: "Silicon-based microelectronics technology is extremely mature, yet this profoundly important material is now also poised to become a foundation for quantum information processing technologies. In this article, we review the properties of silicon that have made it the material of choice for semiconductor-based qubits with an emphasis on the role that modeling and simulation have play... » read more

Manufacturing Bits: Sept. 1

AI, quantum computing R&D centers The White House Office of Science and Technology Policy, the National Science Foundation (NSF), and the U.S. Department of Energy (DOE) have announced over $1 billion in awards for the establishment of several new artificial intelligence and quantum information science (QIS) research institutes in the U.S. Under the plan, the U.S. is launching seven new... » read more

The Quantum IoE

The principle of quantum communication (QC) is that it can transfer a quantum state between locations. The significance of that cannot be overstated. This is what we can look to for the delivery of the super-secure communications networks of the future. This kind of secure communications is made to order for the IoE (and, of course, many other platforms). No matter how simple or complex the ... » read more

Manufacturing Bits: Sept. 16

Making sounds with atoms What is the sound of one hand clapping? Perhaps a better question is what is the sound of an atom? Chalmers University of Technology has demonstrated the ability to make a sound with an atom. More specifically, researchers have made acoustic waves with an artificial atom. In doing so, researchers have demonstrated quantum physics with sound taking on the role of lig... » read more
