Physicists at ETH Zurich and the Barcelona Institute of Photonic Sciences have developed a method to control and expand the quantum wavepacket of levitated nanoparticles, potentially paving the way for matter-wave interference experiments with larger objects by using a technique called quantum squeezing to increase coherence length.
Scientists have demonstrated a novel platform using optically trapped nanoparticles coupled together by photons bouncing between mirrors to overcome the classical-quantum transition challenge and preserve quantum features in the presence of environmental noise. This research, led by Dr. Jayadev Vijayan from The University of Manchester, paves the way for observing quantum phenomena at larger scales and has potential applications in sensor technology for environmental monitoring and navigation. The findings represent a significant leap towards understanding fundamental physics and could narrow the gap between the quantum world and everyday classical mechanics.
Researchers at EPFL have achieved a breakthrough in quantum mechanics by controlling quantum phenomena at room temperature, using an innovative experimental setup that combines quantum physics and mechanical engineering. By creating an ultra-low noise optomechanical system with specialized cavity mirrors and a large mechanical oscillator, they were able to minimize thermal noise and demonstrate optical squeezing, a quantum phenomenon, at room temperature. This achievement opens up new possibilities for quantum technology applications and the study of macroscopic quantum systems.
Researchers at the University of Washington have discovered atomic “breathing” or mechanical vibration between atom layers, which could help encode and transmit quantum information. They also created an integrated device that manipulates these atomic vibrations and light emissions, advancing quantum technology development. The researchers plan to build a waveguide and scale up the system to control multiple emitters and their associated phonon states, enabling the quantum emitters to “talk” to each other, a step toward building a solid base for quantum circuitry.
University of Washington researchers have detected the mechanical vibration between two layers of atoms by observing the type of light those atoms emitted when stimulated by a laser. This new development could lead to a new method for quantum computing, as the researchers have already engineered a device that could serve as a new type of building block for quantum technologies.
Researchers at the University of Washington have discovered that they can detect atomic "breathing" by observing the type of light emitted by atoms when stimulated by a laser. This atomic "breath" could help encode and transmit quantum information. The team also developed a device that could serve as a new type of building block for quantum technologies. The device involves only a small number of atoms and can control multiple emitters and their associated phonon states, enabling quantum emitters to "talk" to each other, a step toward building a solid base for quantum circuitry.
