Quantum computers promise significantly shorter computing times for complex problems. But there are still only a few quantum computers worldwide with a limited number of so-called qubits. However, quantum computer algorithms can already run on […]
With only two levels of superposition, the qubits used in today’s quantum communication technologies have limited storage space and low tolerance for interference. Engineering’s hyperdimensional microlaser generates ‘qudits,’ photons with four simultaneous levels of information. […]
Researchers have created grids of tiny clumps of atoms known as quantum dots and studied what happens when electrons dive into these archipelagos of atomic islands. Measuring the behavior of electrons in these relatively simple […]
Researchers have discovered new waves with picometer-scale spatial variations of electromagnetic fields which can propagate in semiconductors like silicon. Read More Quantum Computers News — ScienceDaily
A new study illustrates how substrates affect electronic interactions in 2D metal-organic frameworks. With electronic properties tuneable by electrical charge, mechanical strain, and hybridization, such structures can be ‘switched’ off and on, allowing potential applications […]
Quantum dots are nanoscale crystals capable of emitting light of different colors. Display devices based on quantum dots promise greater power efficiency, brightness and color purity than previous generations of displays. Of the three colors […]
With the advance of quantum technologies, new microscopy modalities are becoming possible — ones that can see electric currents, detect fluctuating magnetic fields, and even see single molecules on a surface. A prototype of such […]
Quantum dots are clusters of some 1,000 atoms which act as one large ‘super-atom’. It is possible to accurately design the electronic properties of these dots just by changing their size. A team has succeeded […]
Scientists have managed for the first time to create a unidirectional device that significantly increases the quality of a special class of transmitted signals in optical communications: optical vortices. By transmitting selective optical vortex modes […]
Computing power of quantum machines is currently still very low. Increasing it is still proving to be a major challenge. Physicists now present a new architecture for a universal quantum computer that overcomes such limitations […]
