Chinese satellite has been extending QKD

Three years after its launch, the Chinese satellite nicknamed “Micius”  has steadily been extending the reach of an encryption technology that is practically unbreakable. Chinese researchers proved it was possible for photons sharing quantum entanglement […]

First three-photon color entanglement

Researchers at University of Illinois have constructed a quantum-mechanical state in which the colors of three photons are entangled with each other. The state is a special combination, called a W state, that retains some […]

Google Quantum Supremacy?

There have been a lot of hype and buzz since last week. At least, here is a smart article written by a smart guy. Read it up to the end – it’s worth it. Scott’s […]

How to stop a quantum wave?

A research team at University of Buffalo has developed a “traffic light” that can bring quantum waves to a halt. The scientists isolated a specially built nano-conductor at an extremely cold temperature — minus 273 […]

Quantum biosensors with DNA-stabilized metal quantum clusters

Project BioSensing, a collaboration among two of Germany’s Fraunhofer institutes and Dutch Leiden University’s Institute of Physics, was developed to overcome the limits of modern biosensors by applying quantum technology. DNA-stabilized metal quantum clusters (QC-DNAs), […]

Bell state with acoustic waves

Researchers in the University of Arizona Department of Materials Science and Engineering have demonstrated the possibility for acoustic waves in a classical environment to do the work of quantum information processing without the time limitations […]

Google or not Google?

It’s hard not to mention the current breaking news that everyone can read today everywhere, maybe even on tabloids. All the buzz came from a paper which might have been posted on NASA website where […]

New method for detecting quantum states of electrons

Team at Okinawa Institute of Science and Technology (OIST) has discovered a new method, called image charge detection, to detect electrons’ transitions to quantum states. Electron needs to be immobilized to be used as quantum […]

The Poor man’s Quantum Computer

Scientists at the Purdue University built a device that is a modified version of magnetoresistive random-access memory, or MRAM, which some types of computers use today to store information. The technology uses the orientation of […]

A new step toward room temperature quantum computing chips

Researchers at Stevens Institute of Technology have coaxed photons into interacting with one another with unprecedented efficiency which is a key advance toward realizing long-awaited quantum optics technologies for computing, communication and remote sensing. The […]

Progress in noise cancelling for quantum computers

A team from Dartmouth College and MIT has designed and conducted the first lab test to successfully detect and characterize a class of complex, “non-Gaussian” noise processes that are routinely encountered in superconducting quantum computers. […]

True and ‘fake’ Majorana states

Researchers at Uppsala University in Sweden have identified how to distinguish between true and ‘fake’ Majorana states in one of the most commonly used experimental setups, by means of supercurrent measurements. Majorana states have exotic […]

Quantum Hall Effect (QHE) in three dimensions

Researchers at the Singapore University of Technology and Design (SUTD) and the Southern University of Science and Technology in China announces the first experimental demonstration of the QHE (Quantum Hall Effect) in three dimensions. (The […]

Bigger quantum computers? Just build them like Legos

Quantum Circuits, a startup founded in 2017, is networking mini quantum devices together like Legos to create quantum computers easier to scale up. The startup uses quantum teleportation entangling a microwave photon in one module with […]

Novel atomic clock design offers ‘tweezer’ control

Researchers at JILA, a joint research institute operated by the National Institute of Standards and Technology (NIST) and the University of Colorado Boulder, have demonstrated a novel atomic clock design that combines near-continuous operation with […]

Physicists finally nail the proton’s size

In 2010, Randolf Pohl of the Max Planck Institute of Quantum Optics (Quantamagazine) announced his team precisely measured the size of the proton by substituting the electron of a hydrogen atom by a muon. The size […]

NASA has developed a new quantum gravity sensor

The quantum sensor, which NASA has developed with Bay Area-based company AOSense, relies on some 100 million cesium atoms. The device launches the atoms inside a cylindrical column and times how quickly they fall. Atoms […]

What is Quantum probability?

Different approaches to quantum mechanics invoke different meanings of probability. What is “probability”? This very amazing article discusses three of the leading approaches to quantum theory: the “dynamical collapse” theories, such as the GRW model, the […]
