Roadmap: Quantum algorithms and quantum machine learning could assist high-energy physics, ranging from studying neutrino oscillations to reconstructing particle trajectories in colliders.
Researchers have just found evidence of “dark electrons”—electrons you can’t see using spectroscopy—in solid materials.
The achievement marks a way toward “fault-tolerant” quantum computing as it achieved record-low error rates in prototype quantum computer. It’s also expected to lead to the development of more stable quantum computers.
IQM maintains that qubit relaxation time T1 of 0.964 +- 0.092 milliseconds and dephasing time T2 echo of 1.155 +- 0.188 milliseconds was demonstrated on a planar transmon qubit on a silicon chip fabricated in IQM´s own fabrication facilities.
The coherence times, characterized by the relaxation time T1 and the dephasing time T2 echo, are among the key metrics for assessing the performance of a single qubit, as they indicate how long quantum information can be stored in a physical qubit, according to the company.
Proposed experiments will search for signs that spacetime is quantum and can exist in a superposition of multiple shapes at once.

There is a glaring gap in our knowledge of the physical world: none of our well-established theories describe gravity’s quantum nature. Yet physicists expect that this quantum nature is essential for explaining extreme situations such as the very early universe and the deep interior of black holes. The need to understand it is called the problem of “quantum gravity.”
Scientists have just theorized how to connect quantum processors over vast distances to form a giant quantum computing network that acts as a single machine.
Researchers at the Paris Institute of Nanoscience at Sorbonne University have developed a new method to encode images into the quantum correlations of photon pairs, making it invisible to conventional imaging techniques. The study is published in the journal Physical Review Letters.
As scientists and researchers increasingly look to quantum computing to aid in complex problem-solving and advance our understanding of the universe—quantum error correction has become a critical area of scientific inquiry.
, while an interesting thought experiment, does not seem to account for the fact that many phenomena are materialistic or physical enough to have no resemblance with the qualities we typically attribute to consciousness, such as experience and motive.
Panprotopsychism, by contrast, does not require matter to be intrinsically conscious, only that it be comprised of features equaling consciousness when combined.
New research shows that the “superluminal observer” needs three separate time dimensions for a warp-speed math trick that would please even Galileo.
TL;DR
The concept of superluminal observers, proposed by Andrzej Dragan’s team, explores how faster-than-light travel might unify general relativity and quantum mechanics. By introducing three dimensions of time alongside one dimension of space, this research challenges our current understanding of the universe. Quantum phenomena, such as superposition and indeterminism, could be reinterpreted through the lens of a superluminal observer, where space and time swap roles at warp speeds. This theoretical framework suggests that the laws of physics remain consistent even at superluminal speeds, potentially paving the way for a unified field theory that reconciles these two fundamental branches of physics.
With its particles in two places at once, quantum theory strains our common sense notions of how the universe should work. But one group of physicists says we can get reality back if we just redefine its foundations.
