Determining the Hamiltonian of quantum systems with far fewer measurements
The number of measurements needed to characterize a system of quantum particles is far fewer than previously thought, a RIKEN physicist and three collaborators have shown. As well as cutting the workload of experimentalists, this finding has importan.....»»
The end of the quantum tunnel: Exact instanton transseries for quantum mechanics
In the quantum world, processes can be separated into two distinct classes. One class, that of the so-called "perturbative" phenomena, is relatively easy to detect, both in an experiment and in a mathematical computation. Examples are plentiful: the.....»»
Unveiling a new quantum frontier: Frequency-domain entanglement
Scientists have introduced a form of quantum entanglement known as frequency-domain photon number-path entanglement. This advance in quantum physics involves an innovative tool called a frequency beam splitter, which has the unique ability to alter t.....»»
TESS finds its first rogue planet
Well over 5,000 planets have been found orbiting other star systems. One of the satellites hunting for them is TESS, the Transiting Exoplanet Survey Satellite. Astronomers using TESS think they are made a rather surprising discovery; their first free.....»»

Demonstration of heralded three-photon entanglement on a photonic chip
Photonic quantum computers are computational tools that leverage quantum physics and utilize particles of light (i.e., photons) as units of information processing. These computers could eventually outperform conventional quantum computers in terms of.....»»
Applying DevSecOps principles to machine learning workloads
Protecting data and other enterprise assets is an increasingly challenging task, and one that touches nearly every corner of an organization. As the complexity of digital systems grows, the challenges mount. One method that helps reign in the chaos i.....»»
A molecular fingerprint beyond the Nyquist frequency
Ultrashort pulses play a significant role in spectroscopic applications. Their broad spectral bandwidth enables simultaneous characterization of the sample at various frequencies, eliminating the need for repeated measurements or laser tuning. Moreov.....»»
Scientists tune the entanglement structure in an array of qubits
Entanglement is a form of correlation between quantum objects, such as particles at the atomic scale. The laws of classical physics cannot explain this uniquely quantum phenomenon, yet it is one of the properties that explain the macroscopic behavior.....»»
Leaf size and defensive traits found to modulate effects of soil fauna on litter decomposition
Leaf litter, as a multifunctional legacy of plants, plays an essential role in driving biogeochemical cycles, while providing important habitat and food resources for soil organisms. Litter traits and soil fauna play a crucial role in determining lit.....»»
New model extends theory of pattern formation to the nano-cosmos
A new model developed by scientists from the Max Planck Institute for Dynamics and Self-Organization (MPI-DS) extends the theory of elastic phase separation towards nanoscopic structures. Such patterns are frequent in biological systems and also used.....»»
Social change may explain decline in genetic diversity of the Y chromosome at the end of the Neolithic period
The emergence in the Neolithic of patrilineal social systems, in which children are affiliated with their father's lineage, may explain a spectacular decline in the genetic diversity of the Y chromosome observed worldwide between 3,000 and 5,000 year.....»»
