An ir-vis interface for qubits could connect fine quantum computers via glass fibers
Swiss researchers have built an interface for optical qubits to be implemented between photons of different wavelengths, here from the visible in the infrared spectral range. To replace qubits, pairs of worried photons are suitable. If the optical excitation energy is of an atom, which stores a qubit, in the visible, then the qubit now can now send by means of fiber in the infrared wavelength range.
Alkali atoms can absorb or transmit visible light, see, for example, orange luminous sodium vapor lamps of the strain lighting. The luminous electrons of this cum grano salesis hydrogenahn atoms are suitable for storing qubits (cf.Quantum computers will have a bad thought) in terms of quantum computers (cf. Basic research for quantum computer). However, a qubit alone does not yet make a quantum computer coupled to qubits, for example, visually, which is not quite trivial.
