Heisenberg Uncertainty Principle and Quantum Information, Both Under the Microscope
A football is not a quantum particle. There are crucial differences between the things we know from everyday life and tiny quantum objects. Quantum phenomena are usually very fragile. To study them, one normally uses only a small number of particles, well shielded from the environment, at the lowest possible temperatures.

Imaging Nitrogen-Vacancy Centers Just Got a Whole Lot Clearer
Seeing with Radio Waves Researchers at the University of Tsukuba use radio-frequency waves to image “spin-locked” defects in diamond with record-breaking resolution, which may lead to advances in material characterization and quantum computing Scientists from the Division of Physics at the University of Tsukuba used the quantum effect called “spin-locking” to significantly enhance the resolution […]

Indiana U.S.A. is to Lead Coalition for Developing Quantum Technologies
Purdue to lead Indiana coalition to develop quantum technologies Purdue University is leading efforts to establish a National Science Foundation-backed quantum research center that would bring dozens of scientists from four research partners and industry together to tackle applied research in the field. The new Center for Quantum Technologies will be established through the NSF’s Industry-University […]
U. of Basel Effort: Quantum Tech. to Benefit From Ultrathin Semiconductors Connected to Superconductors
For the first time, University of Basel researchers have equipped an ultrathin semiconductor with superconducting contacts. These extremely thin materials with novel electronic and optical properties could pave the way for previously unimagined applications. Combined with superconductors, they are expected to give rise to new quantum phenomena and find use in quantum technology.
U.S. Gov’t Agencies Should Consider Quantum Computing in Risk Assessments
Why quantum and data protection should go hand in hand Read More… + The era of quantum computing is fast approaching, and with it the greatest threat to cryptography at a scale never seen before. A quantum computer will be able to break RSA-2048, considered the gold standard for Public Key Encryption (PKE), the system […]
High-Temperature Superconductors Get Lanthanhum and Yttrium Added to Their List
A team led by Skoltech professor Artem R. Oganov studied the structure and properties of ternary hydrides of lanthanum and yttrium and showed that alloying is an effective strategy for stabilizing otherwise unstable phases YH10 and LaH6, expected to be high-temperature superconductors. The research was published in the journal Materials Today. Cuprates had long remained […]
Researchers Continue the Quest for the Perfect Qubit
Quantum computers promise great advances in many fields – from cryptography to the simulation of protein folding. Yet, which physical system works best to build the underlying quantum bits is still an open question. Unlike regular bits in your computer, these so-called qubits cannot only take the values 0 and 1, but also mixtures of the two. While this potentially makes them very useful, they also become very unstable.
