‘There is no such thing as past or future’: physicist Carlo Rovelli

“If the theory of general relativity describes a world of curved spacetime where everything is continuous, quantum theory describes a world in which discrete quantities of energy interact” writes Charlotte Higgins for theguardian.com. In The Order of Time, he asks why can we know only the past, and not the future?. Rovelli’s work as a physicist, in crude terms, occupies the large space left by Einstein on the one hand, and the development of quantum theory on the other. Source: theguardian.com Share This:

Weird vibrations poised to control quantum computers

“First, physicists must learn to control quantum vibrations” writes Adrian Cho for sciencemag.org. The budding discipline of quantum acoustics could shake up embryonic quantum computers by miniaturizing technologies and producing longer-lasting quantum memories.However, that simple quantum state persisted for just 5 nanoseconds, too little time to put the device into more complex quantum states of motion.Los Angeles, California—For the moment, microwave photons are the keys to many quantum computers: Physicists use them to program, read out, and otherwise manipulate the machines’ quantum bits.And by connecting the transducer to a superconducting…

Scientists Propose Experiment to Test Quantum Gravity

“Two groups of scientists may have finally solved that problem, by proposing an experiment to determine if the graviton exists without ever observing it directly” writes Avery Thompson for popularmechanics.com. If the experiment is successful, it would prove that gravity and quantum mechanics can be reconciled.This might seem like a roundabout way of finding out if quantum gravity exists, but it’s probably the only way available to physicists.If it does, however, finding it could help solve one of the biggest problems in physics and unify gravity with quantum mechanics. Source: popularmechanics.com…

Bristlecone: Google’s new 72-qubit quantum computing chip is the most advanced of its kind by far

“Google has unveiled its new quantum computing processor called Bristlecone and it is expected to help the search engine giant achieve “quantum supremacy” in the future” writes Kukil Bora for ibtimes.co.in. “We are cautiously optimistic that quantum supremacy can be achieved with Bristlecone,” Google research scientist Julian Kelly said in a statement.Although many other tech giants like IBM, Microsoft and Intel are also heavily investing to build practical quantum computers, no one has so far achieved the goal of quantum supremacy.Quantum supremacy refers to the state in which a quantum computer…

Quantum computing is finally here, and a Canadian company has a plan to bring it to the masses

“Existing investors include In-Q-Tel, the venture group that invests on behalf of the CIA, and Jeff Bezos’ venture firm” writes Ari Levy for cnbc.com. His Vancouver-based company first raised venture funding back in 2004, five years before he joined.Vern Brownwell spent the past eight years preaching quantum computing to a world that wasn’t ready for it. Source: cnbc.com Share This:

Cardano Foundation Publishes Research on Threat of Quantum Computing

“The Cardano Foundation and think-tank Z/YN recently released their findings on this potential threat to public key cryptography” reports newsbtc.com. The Cardano Foundation wants to lead the charge in addressing future issues associated with quantum computing.The study concludes how large-scale quantum computing will effectively break the security of public key cryptography. Source: newsbtc.com Share This:

Intel Touts New Quantum Computing Breakthrough, This Time With Silicon

“Note: This is a fundamentally different technology than the quantum computing research Intel unveiled earlier this year” writes Joel Hruska for extremetech.com. First and foremost, Intel is heavily invested in the silicon industry — far more so than any other firm working on quantum computing.This could be critical to efforts to scale quantum computing systems upwards.When it comes to quantum computing, however, silicon-based solutions haven’t really been adopted. Source: extremetech.com Share This:

While you were glued to Twitter, a high-tech job passed you by | Thomas Friedman / Syndicated columnist

“Quantum computers, with their exponential processing power, will be able to crack most encryption without breaking a sweat” writes Thomas Friedman for seattletimes.com. Last week I visited the same lab, where my hosts showed me the world’s first quantum computer that can handle 50 quantum bits, or qubits, which it unveiled in November.Talia Gershon, an IBM researcher, posted a fun video explaining the power of quantum computers to optimize and model problems with an exponential number of variables.The result is computers that may one day “operate 100,000 times faster than…

After years of avoidance, Department of Energy joins quest to develop quantum computers

“The U.S. Department of Energy (DOE) is joining the quest to develop quantum computers, devices that would exploit quantum mechanics to crack problems that overwhelm conventional computers” writes Adrian Cho for sciencemag.org. Quantum computers might also aid in the design of materials from their atomic constituents on up.That’s how a quantum computer could quickly factor large numbers, potentially enabling it to crack current internet encryption protocols.However, it is the way quantum computers solve problems that accounts for their power—and their limitations.The initiative comes as Google and other companies race to…
