A blueprint for building a quantum computer
... are of course tiny, ion traps are limited to inter-atom spacing of perhaps tens of microns for RF and optical control. Nanophotonic systems will require components tens of microns across, to accommodate the 1.5μm wavelength light that is desirable for telecommunications and silicon optics. Supercond ...

... The ”B” in the acronym refers to the assumption that the error probability, p = P [M accepts x] for x 6∈ L (or vice versa), is bounded away from 1/2. To be consistent we will always set p = 1/3. However, the choice of p is irrelevant as long as there is some fixed (or even an inversely polynomial in ...

... near future energies available in accelerator physics. This second scenario suggests that QM, as we know it today, might fail not only above the 10 TeV scale, but also that one could find unexpected effects at the quantum level for phenomena with a characteristic scale of 10−2 − 10−4 eV, for example ...

Private Quantum Channels
... have the resource of shared randomness, which is weaker but easier to maintain. A first question is: is it at all possible to send quantum information fully securely using only a finite amount of randomness? At first sight this may seem hard: Alice and Bob have to “hide” the amplitudes of a quantum ...

The Fano effect in electrical conductance occurs when the phase of electron wave in the non-resonant channel changes insignificantly within the energy Γ centred at the resonance level, where Γ stands for the discrete level width. The Fano line shape in various QD systems has been recently observed e ...

Why is there an invariant speed c?
... Thus the signal moving with speed c in S1 also moves with speed c in S2. This result also means that when a signal moves in the x direction with speed c in a frame S2, its speed is also c in the frame S1 with velocity in the -x direction relative to S2. ...
