Quantum motion and hyperentanglement control
The two atoms trapped in the beam of laser light are shown in a special quantum state called hyperentanglement. In this state, both motion and internal energy are linked, opening up new possibilities for quantum technology. Credit: AI-generated images by Manuel Endres Manuel Endres, professor of physics at Caltech, specializes in finely controlling a single atom using a device known…

First successful demonstration of quantum error correction in quantum computer qudits
Realization of logical GKP Ququart. Credit: Nature (2025). doi: https://doi.org/10.1038/S41586-025-08899-y In the world of quantum computing, the dimensions of Hilbert space (a measure of the number of quantums accessible to quantum computers) are respected possessions. Larger Hilbert spaces allow for more complex quantum behavior and play an important role in enabling quantum error correction (QEC). This is essential to protect…

Australian researchers use quantum computers to simulate the behavior of real molecules
Graphical abstract. Credit: Journal of the American Chemical Society (2025). doi:10.1021/jacs.5c03336 When molecules absorb light, they receive a whirlwind of quantum mechanical transformation. Electrons jump between energy levels, oscillations of atoms, and chemical bonds, all within 10 seconds. These processes support everything from photosynthesis in plants to DNA damage caused by sunlight, to solar cell surgery and light-driven cancer therapy.…

Electro-Optic Sampling Research unlocks new insights into quantum physics
(a) Evolution of the polarization states of incoming field geometry, electro-optic crystals (EOX), and gate pulses. (b) Typical setup of EOS using a femtosecond laser. The near-infrared (NIR) laser power in the form of a short pulse (blue) is split into “test” and “gate” beams by a beam splitter (BS). For example, the long wave test wave (red) produced by…

New research provides insight into the cleanup of quantum entanglement noise
Researchers have found that a universal entanglement purification protocol is not guaranteed to improve the fidelity of entangled states in all possible quantum systems. Credit: Zhong Lab Quantum Entanglement – The connections between particles that generate correlations beyond what is classically possible will become the backbone of future quantum technologies, such as secure communication, cloud quantum computing, and distributed sensing.…

Physicists discover rare chiral quantum states in topological materials
Credits: Shafayat Hossain and Zahid Hasan Lab Chirality – The properties of objects that differ from their mirror image were scientists who were long fascinated across biology, chemistry and physics. This phenomenon is sometimes called “dominant hand.” This is because it refers to an object that owns a clear left or right-handed form. It is a universal quality found on…

Alternate black hole models suggest that quantum effects may eliminate the need for singularities
A singular black hole and non-stringed instrument alternative. Credit: Sissa Mediaab. Background images sourced from ESO/Cambridge Astronomical Survey Unit (eso.org/public/images/ESO1101A/) Ever since the theory of general relativity pointed out the existence of black holes, the scientific community has been wary of one unique feature. It’s central idiosyncratic. This hides behind the horizon of events where the laws of physics governing…

Quantum confinement explains a dramatic increase in electrical resistivity in silicon sheets of several nanometers thick
Schematic diagram of semiconductor ultra-thin film credits: alessio zaccone with chatgpt Consumer electronics are primarily made from silicon, germanium, copper, and materials that have been used for over 60 years. Why is semiconductor electronics becoming faster and faster this time? I argue that this is due to miniaturization or the ability to stack more and more transistors in tightly integrated…
