In the early days of research on black holes, before they even had that name, physicists did not yet know if these bizarre objects existed in the real world. They might have been a quirk of the complicated math used in the then still young general theory of relativity, which describes gravity. Over the years, though, evidence has accumulated that black holes are very real and even exist right here in our galaxy.

A quantum charged coupled device – a type of trapped-ion quantum computer first proposed 20 years ago – has finally been fully realized by researchers at Honeywell in the US. Other researchers in the field believe the design, which offers notable advantages over other quantum computing platforms, could potentially enable quantum computers to scale to huge numbers of quantum bits (qubits) and fully realize their potential.

Fermilab's Muon g-2 experiment shows results inconsistent with the standard model predictions.

Wormholes play an essential role in various science fiction films — connecting two distant points in space. However, According to physics, these tunnels in spacetime are purely theoretical. Dr. Jose Luis Blázquez-Salcedo from the University of Oldenburg supervised an international team that has now introduced a new theoretical model in the science journal Physical Review Letters that make microscopic wormholes appear less far-fetched than in earlier theories.

California researchers discovered a way to leverage an unused property of light to apply the unrestricted nature of the quantum domain to wireless communication, creating a new type of channel with infinite capacity that could make looming data limitations irrelevant.

Researchers have found a way to speed up the search for dark matter using technology from quantum computing. By squeezing quantum noise, detectors can now look for axions twice as fast.

For almost a century, researchers have worked to unravel the mystery of dark matter — an elusive substance that spreads through the universe and likely makes up a lot of its mass, however has so far proven impossible to detect in experiments. Presently, a group of researchers has used an innovative method called “quantum squeezing” to dramatically speed up the search for one candidate for dark matter in the lab.

University of Copenhagen researchers have advanced their quantum technology to such a degree that classical computing technology can no longer keep up. They have developed a chip that, with financial backing, could be scaled up and used to build the quantum simulator of the future. Their results are now published in Science Advances.

Quantum mechanics is strange. A philosopher explains just how strange, and what it means for reality.

A team of researchers claim to have achieved sustained, long-distance quantum teleportation for the first time. The research could lay the groundwork for “a viable quantum internet — a network in which information stored in qubits is shared over long distances through entanglement” that could “transform the fields of data storage, precision sensing and computing,” according to a Fermilab statement.

The breakthrough, made by researchers at Caltech, Fermilab and NASA, among others, is a step towards a practical quantum internet.

In a landmark series of calculations, physicists have proved that black holes can shed information, which seems impossible by definition.

It has been thought of as many things: a pointlike object, an excitation of a field, a speck of pure math that has cut into reality. But never has physicists’ conception of a particle changed more than it is changing now.

Passing electricity through a piece of quartz crystal generates a pulse you can literally set your watch by. Set a time crystal melting, on the other hand, and it just might pulse with the deepest secrets of the Universe.

The world is one step closer to having a totally secure internet and an answer to the growing threat of cyber-attacks, thanks to a team of international scientists who have created a unique prototype that could transform how we communicate online.

In an incredible example of cosmic scales meeting the tiniest possible realm, scientists found that radiation including cosmic rays causes superconducting qubits to slip into disarray.

The existence of time crystals - a particularly fascinating state of matter - was only confirmed a few short years ago, but physicists have already made a pretty major breakthrough: they have induced and observed an interaction between two time crystals.

MIP* = RE is not a typo. It is a groundbreaking discovery and the catchy title of a recent paper in the field of quantum complexity theory. Complexity theory is a zoo of “complexity classes” – collections of computational problems – of which MIP* and RE are but two.

No one likes noise when they’re working through a difficult problem. Quantum computers are no different, and now researchers have devised a new way to estimate how noise can throw their calculations off, a big step towards making the technology practical. The quantum states at the heart of today’s quantum computers are fragile things. They are highly susceptible to disturbances from everything from stray magnetic fields to the minuscule imperfections in the control electronics or materials used to build the device.

Amazon today launched its fully managed quantum computing service -- Braket -- in general availability, following a preview.
