A graph based on the researchers’ equations ... The study authors made two assumptions to understand the unidirectional flow of time in a quantum system. Their first assumption was that the ...

for graph classification. We commence by performing the Continuous-time Quantum Walk (CTQW) on each graph structure, and compute the Averaged Mixing Matrix (AMM) to describe how the CTQW visits all ...

The team tested graph coloring in simulations of large hydrogen model systems, which are incredibly complex testbeds—simple chemical compositions that demand quick quantum data preparation ...

"These quantum computer algorithms were originally developed in a completely different context. We used them here for the first time to calculate electron densities of molecules, in particular ...

The researchers emphasise that these perplexing results highlight a peculiar quirk of quantum mechanics rather than a radical shift in our understanding of time. "This is tough stuff, even for us ...

Here’s how it works. Scientists have successfully transmitted quantum data and conventional data through a single optical fiber for the first time. The research demonstrates that quantum data in ...

"A negative time delay may seem paradoxical, but what it means is that if you built a 'quantum' clock to measure how much time atoms are spending in the excited state, the clock hand would ...

Measuring values of the electrons' momenta and plotting them out on a three-dimensional graph ... for the first time. This massless particle essentially functions like a super-efficient electron, and ...

Now, researchers at the University of Toronto, through innovative quantum experiments, say they have demonstrated that "negative time" isn't just a theoretical idea, it exists in a tangible ...

While today gives way to tomorrow and the day after and so on in the real world, new findings show that time can flow in ...
