A new study published in Frontiers in Computer Science investigated if placing smartphones just out of our reach while we’re at work influenced device use for activities not related to work.
“The study shows that putting the smartphone away may not be sufficient to reduce disruption and procrastination, or increase focus,” said the paper’s author Dr. Maxi Heitmayer, a researcher at the London School of Economics. “The problem is not rooted within the device itself, but in the habits and routines that we have developed with our devices.”
A quantum state of light was successfully teleported through more than 30 kilometers (around 18 miles) of fiber optic cable amid a torrent of internet traffic – a feat of engineering once considered impossible.
The impressive demonstration by researchers in the US in 2024 may not help you beam to work to beat the morning traffic, or download your favourite cat videos faster.
However, the ability to teleport quantum states through existing infrastructure represents a monumental step towards achieving a quantum-connected computing network, enhanced encryption, or powerful new methods of sensing.
Ten years ago, researchers proved that adding full memory can theoretically aid computation. They’re just now beginning to understand the implications.
In a new study published by researchers at quantum computing company Quantinuum and collaborators from Caltech, Fermioniq, EPFL, and the Technical University of Munich, scientists have used Quantinuum’s powerful quantum computer, H2, to simulate a notoriously difficult system—quantum magnetism —in a way that pushes beyond what classical computers can reliably achieve.
“Digital quantum computers are much more flexible/universal, but we have paid for that flexibility with many technical challenges,” Dr. Michael Foss-Feig of Quantinuum and the paper’s lead author told the Debrief.
“This paper is an indication that we are finally moving these more flexible/universal machines into the realm of practical (and scientifically illuminating) quantum simulation,” Foss-Feig said.
Do quantum effects in our body provide neurons with their incredible information processing power?
Scientists at QuTech have achieved a major milestone in quantum computing by creating highly precise quantum gates on a diamond chip, hitting error rates as low as 0.001%. By using ultra-pure diamonds and advanced gate designs, the team overcame key challenges that have limited previous approache
In an attempt to speed up quantum measurements, a new Physical Review Letters study proposes a space-time trade-off scheme that could be highly beneficial for quantum computing applications.
Quantum computing has several challenges, including error rates, qubit stability, and scalability beyond a few qubits. However, one of the lesser-known challenges quantum computing faces is the fidelity and speed of quantum measurements.
The researchers of the study address this challenge by using additional or ancillary qubits to significantly reduce measurement time while maintaining or improving the quality of measurements.
