Physicists save Schrödinger’s cat and bring us closer to quantum computers

The quantum jump that kills Schroedinger’s cat isn’t as sudden or random as previously believed. There is hope for our kitty yet!

You can now tinker around with IBM’s quantum computers – straight from your couch

Quantum computing is still in its infancy, but you can test drive it yourself thanks to IBM.

Two-qubit silicon quantum computer works for the very first time

Quantum computing is one of the future’s transitional technologies destined to transform human society, along with advanced materials like graphene and metallic glass or advances in space propulsion. Imagine what the transition from vacuum tubes to transistors did for computing, scale that a couple of folds and you might somewhat be close to what quantum computers are capable of. Operations that today’s supercomputers require days even weeks to crunch, would be completed immediately by leveraging the quantum weirdness that happens below the nano scale. All of this is theoretically possible – but in practice building a working quantum computer that doesn’t disintegrate information has proven to be an immense challenge. We’re still far from there, but advances reported by Australian researchers hint that quantum computers aren’t a pipe dream.

The quest for the quality qubit: quantum computer based on trapped ions has error rate of only 0.07%

Who would’ve thought only a decade ago that quantum computers would become real in the upcoming future? Those of us without such hindsight need to rely on what’s been reported by scientists, and recently all kinds of developments lend us to think that a quantum computing future isn’t that far off. Take the latest qubit experimental set-up made at University

Milestone algorithm runs for the first time on a quantum computer

A 20-year-old algorithm that demonstrated the benefit of using quantum mechanics to solve certain problems has finally been run on a quantum computer – a sweet delicious treat, and a sign that serious progress is being made in the field of quantum computing. The Quantum world is weird A quantum computer is a computation system that makes direct use of

Direct measurement of Van der Waals force made for the first time

Scientists at the Laboratoire Charles Fabry (LCF) in Palaiseau and the University of Lille have for the very first time performed a direct measurement of a Van der Waals force – the weak intermolecular force that causes, in some cases when there isn’t a strong force present, to attract and “stick” to one another. The Van der Waals force is what

New technique bypasses Heisenberg’s Uncertainty Principle

A group of researchers at University of Rochester and the University of Ottawa have found a way to bypass Heisenberg’s famous Uncertainty Principle, and measure key quantum properties directly for the first time like the polarization states of light. The technique might provide valuable in encoding qubits, the building blocks of quantum information theory. Heisenberg’s Uncertainty Principle states that when certain properties

Researchers make breakthrough in quantum computation: factoring a number in prime numbers

If you did intermediate math in school, then you’ll most likely remember how to split numbers into prime factors; basically, any number can be written out by multiplying prime factors. Now, a group of researchers from UC Santa Barbara has designed and fabricated a quantum processor capable of factoring a composite number. Don’t get overexcited though, because the number is

Quantum computers will be able to simulate particle collisions [w/ video]

Effective quantum computers are still far away, but researchers are already showing more and more advantages these devices would bring to the table. A trio of theorists have shown one more talent of a quantum computer: it would be powerful enough to study the inner workings of the universe in ways that are far beyond the reach of even the

First-ever working quantum network lays foundation for the future’s quantum internet

Quantum technology is the future, no doubt. The impact of computing devices based on quantum effects finally entering service would be vast and of immense positive consequence to the scientific world, and hence mankind, comparable with the invent of the microchip. While this future might still seem far fetched, judging from the number of successful efforts we’ve witnessed in the

Scientists devise qubits in a semiconductor for the first time

Hailed as yet another big step towards devising working quantum computers, scientists at Ruhr-Universität Bochum (RUB) have successfully managed to generate quantum qubits inside a semiconductor for the first time, instead of vacuum. A qubit is the quantum analog of a bit. While a bit must be read either as a 0 or 1, the qubit can be read as 0, as

IBM makes significant breakthrough towards scalable quantum computers

During the past months we’ve been reporting several breakthroughs in the field of quantum computing, and now IBM seems ready to truly pave the way for quantum computers. Researchers announced they are now able to develop a superconducting qubit made from microfabricated silicon that maintains coherence long enough for practical computation. Whoa! That probably sounds like a lot to swallow,

Quantum computers one step closer to reality

Physicists from Rice University have made an important break through in the field of quantum computing, after creating a tiny “electron superhighway”, critical for the development of the first working quantum computer. The quantum computer is thought to revolutionize the computing scene of the future, and is believed by many to hold the same impact that microprocessors first had in

Quantum information stored in a single atom

It’s amazing where computer science is heading to, and with quantum computing getting more and more popular, the trend of evolving towards smaller and smaller scales has just reached another level – an atomic level. Gerhard Rempe at the Max Planck Institute of Quantum Optics in Garching have stored quantum information in a single atom! This new method will help

Big leap for quantum computing

Quantum computers – closer thank you think   The microprocessors used today are absolutely amazing on their own; it seemed, and for good reason, that there was little we could do to improve them. If anything was to top microprocessors, it would have to be something from a totally different league, which is just down right hard. But then, the

Ultrafast quantum computers one step closer

Researchers from the Oxford University have outdone themselves, successfully generating 10 billion bits of quantum entanglement in silicon for the first time, which represents a significant step towards an ultrafast quantum computer, because entanglement is the key element that should make quantum computers way more powerful than “traditional” computers. In order to achieve this, the Oxford scientists used low temperatures

First Universal Two-Qubit quantum processor created

Physicists from NIST (National Institute of Standards and Technology) have demonstrated what they claim to be the first universal programmable quantum information processor that will be able to run any program allowed by quantum mechanics (the set of principles that describe the atomic and subatomic matter). They managed to accomplish this using two quantum bits (qubits) of information. This processor
