Fewer qubits but higher fidelity, and a promise of rapid advances.

Physicists at Aalto University and VTT Technical Research Center of Finland have developed a new detector for measuring energy quanta at unprecedented resolution. This discovery could help bring quantum computing out of the laboratory and into real-world applications. The results have been published today in Nature.

The type of detector the team works on is called a bolometer, which measures the energy of incoming radiation by measuring how much it heats up the detector. Professor Mikko Möttönen’s Quantum Computing and Devices group at Aalto has been developing their expertise in bolometers for quantum computing over the past decade, and have now developed a device that can match current state-of-the-art detectors used in quantum computers.

“It is amazing how we have been able to improve the specs of our bolometer year after year, and now we embark on an exciting journey into the world of quantum devices,” says Möttönen.

Quantum computers, which harness the strange probabilities of quantum mechanics, may prove revolutionary. They have the potential to achieve an exponential speedup over their classical counterparts, at least when it comes to solving some problems. But for now, these computers are still in their infancy, useful for only a few applications, just as the first digital computers were in the 1940s. So isn’t a book about the communications network that will link quantum computers — the quantum internet — more than a little ahead of itself?

Surprisingly, no. As theoretical physicist Jonathan Dowling makes clear in Schrödinger’s Web, early versions of the quantum internet are here already — for example, quantum communication has been taking place between Beijing and Shanghai via fiber-optic cables since 2016 — and more are coming fast. So now is the perfect time to read up.

Dowling, who helped found the U.S. government’s quantum computing program in the 1990s, is the perfect guide. Armed with a seemingly endless supply of outrageous anecdotes, memorable analogies, puns and quips, he makes the thorny theoretical details of the quantum internet both entertaining and accessible.

D-Wave today launched its next-generation quantum computing platform available via its Leap quantum cloud service. The company calls Advantage “the first quantum computer built for business.” In that vein, D-Wave today also debuted Launch, a jump-start program for businesses that want to begin building hybrid quantum applications.

“The Advantage quantum computer is the first quantum computer designed and developed from the ground up to support business applications,” D-Wave CEO Alan Baratz told VentureBeat. “We engineered it to be able to deal with large, complex commercial applications and to be able to support the running of those applications in production environments. There is no other quantum computer anywhere in the world that can solve problems at the scale and complexity that this quantum computer can solve problems. It really is the only one that you can run real business applications on. The other quantum computers are primarily prototypes. You can do experimentation, run small proofs of concept, but none of them can support applications at the scale that we can.”

D-Wave has launched next-gen quantum computing platform Advantage, and Launch, a service to help businesses build hybrid quantum applications.

A team of researchers at the Niels Bohr Institute, University of Copenhagen, have succeeded in entangling two very different quantum objects. The result has several potential applications in ultra-precise sensing and quantum communication and is now published in Nature Physics.

Entanglement is the basis for quantum communication and quantum sensing. It can be understood as a quantum link between two objects which makes them behave as a single quantum object.

Researchers succeeded in making entanglement between a mechanical oscillator—a vibrating dielectric membrane—and a cloud of atoms, each acting as a tiny magnet, or what physicists call “spin.” These very different entities were possible to entangle by connecting them with photons, particles of light. Atoms can be useful in processing quantum information and the membrane—or mechanical quantum systems in general—can be useful for storage of quantum information.

A new study proves that far from being mere mathematical artifacts, particles that are indistinguishable from one another can be a potent resource in real-world experiments.

Since we live in a world which isn’t random, but organized at every level, a role for consciousness seems unavoidable. The ‘digital theologian’ shows us compelling evidence from quantum mechanics, mathematics and computer sciences, which not only aligns with a philosophical worldview of the Primacy of Consciousness, but which also assigns a role to information as its modus operandi.

It is quantum mechanics which appears to connect the Universe as a whole to consciousness. A whole, which is more than the sum of its parts and irreducible to mere assumptions deriving from the anatomizing dissection into mental confabulations. Drawing from the holographic principle, perceptroniums and noocentrism, Alex provides crucial keys to unlock the mystery of consciousness to show us how our local consciousness can arise from a non-local cosmic consciousness network.
