They now plan to create more realistic simulations that will allow them to model how environmental factors such as temperature can affect interactions. Through further improvements, their results could lead to a wide range of applications for quantum dots including quantum bits (qubits) that can ...
A spatial resolution of 30 nm (=λ/31) exceeding the diffraction limit is achieved by super-resolution fluorescence microscopy. The nanoscopic imaging scheme can be applied to coherent quantum-mechanical systems such as quantum dots, as well as colour centres. ...
Semiconductor heterostructure for implementation of quantum computation by using spins of electrons, confined in individual quantum dots, as qubits. There are many different schemes that can be used by employing this concept. One approach is based on electron–hole pairs, also known as excitons, ...
Still in the world of optics, quantum dots are being hailed as a breakthrough technology in the development of more efficient solar cells. In a traditional solar cell, photons of sunlight knock electrons out of a semiconductor into a circuit, making useful electric power, but the efficiency of...

Bill Bialek, too, spoke about inference. But Bill is a Princeton biophysicist, so fruit flies preoccupy him more than qubits do. A fruit fly metamorphoses from a maggot that hatches from an egg. As the maggot develops, its cells differentiate: some form a head, some form a tail, and so...
Time-domain oscillations between distant spin qubits coupled via virtual photons In a device comprising two double quantum dots separated by a 250-μm-long superconducting resonator, virtual photons in the resonator are shown to mediate the coupling of electron spins between the quantum dots. When ...

Trapped ion qubits:Trapped ion particles can also be used as qubits and are noted for long coherence times and high-fidelity measurements. Quantum dots:Quantum dots are small semiconductors that capture a single electron and use it as a qubit, offering promising potential for scalability and compat...
Qubits based on quantum dots are studied worldwide as they are considered a compelling platform for the construction of a quantum computer. The most popular approach is to trap a single electron and to apply a sufficiently large magnetic field, allowing the spin of the electron to be used as...
