Researchers at Technical University of Denmark describe how they have created a ‘carpet‘ of thousands of quantum-mechanically entangled light pulses at room temperature . The discovery has the potential to pave the way for more […]
Researchers at the Joint Quantum Institute (JQI) and the Joint Center for Quantum Information and Computer Science (QuICS) have stretched out multiple photons and turned three distinct pulses into overlapping quantum waves. The work, which […]
Researchers at the University of Geneva (UNIGE), Switzerland, have discovered a new quantum property: by placing 3 pairs of photons in a network, it is possible to entangle them and create new ultra-strong correlations. Entanglement […]
The processing in quantum-based machines is noisy, which produces error rates dramatically higher than those of silicon-based computers. So quantum operations are repeated thousands of times to make the correct answer stands out statistically from […]

Researchers from Purdue University and the University of Rochester demonstrate a new method of relaying information by transferring the state of electrons. Quantum error correction requires that individual qubits interact with many other qubits. But two […]
Three years after its launch, the Chinese satellite nicknamed “Micius” has steadily been extending the reach of an encryption technology that is practically unbreakable. Chinese researchers proved it was possible for photons sharing quantum entanglement […]

Scientists at University of Buffalo report that they can manipulate the electronic properties of this super-thin material in ways that could be useful for encoding quantum data.
You’ve seen the stories—in the Financial Times, Technology Review, CNET, Facebook, Reddit, Twitter, or elsewhere—saying that a group at Google has now achieved quantum computational supremacy with a 53-qubit superconducting device. While these stories are easy to find, I’m not going to link to them here, for the simple reason that none of them were supposed to exist yet.
Quantum mechanics and the general theory of relativity are two pillars of modern physics. However, a coherent unified framework of the two theories still remains an open problem. Attempts to quantize general relativity have led […]
A research team at University of Buffalo has developed a “traffic light” that can bring quantum waves to a halt. The scientists isolated a specially built nano-conductor at an extremely cold temperature — minus 273 […]
