We wrote last September about Dell’s first step in quantum computing to test a solution that integrates their Dell EMC PowerEdge R740xd with IBM Qiskit quantum emulator. They have now taken a second step to test […]
Researchers have developed highly efficient, on-chip frequency shifters that can convert light in the gigahertz frequency range. The frequency shifters are easily controlled, using continuous and single-tone microwaves. Click to rate this post! [Total: 0 […]
Last month, we presented three puzzles that seemed ordinary enough but contained a numerical twist. Hidden below the surface was the mysterious transcendental number e. Most familiar as the base of natural logarithms, Euler’s number […]
The ability to precisely control and change properties of a photon, including polarization, position in space, and arrival time, gave rise to a wide range of communication technologies we use today, including the Internet. The […]
Dell Technologies reports that the company partnered with IonQ to test a hybrid classical-quantum platform, according to Dell’s blog post. The platform allows classical and quantum simulation workloads to be executed on-premises, while quantum workloads, […]
Physicists have created a new ultra-thin, two-layer material with quantum properties that normally require rare earth compounds. This material, which is relatively easy to make and does not contain rare earth metals, could provide a […]
Suppose you are trying to transmit a message. Convert each character into bits, and each bit into a signal. Then send it, over copper or fiber or air. Try as you might to be as […]
Quantum 5, 587 (2021). https://doi.org/10.22331/q-2021-11-24-587 We present two new results about exact learning by quantum computers. First, we show how to exactly learn a $k$-Fourier-sparse $n$-bit Boolean function from $O(k^{1.5}(log k)^2)$ uniform quantum examples for […]
Researchers from Basel and Bochum have succeeded in addressing an apparently unattainable energy transition in an artificial atom using laser light. Making use of the so-called radiative Auger process, they were the first team to […]
Kicking the quantum cybersecurity can down the road my be a potentially devastating delay tactic, a team of cybersecurity experts and quantum information scientists warn. While current quantum computers may not be a threat to […]
