How can a quantum gate be constructed to evaluate a blackbox function (as in the Deutsch's algorithm)?
The standard Deutsch's algorithm uses a control-U gate, which takes the control qubit state $x$ as input to get the output from a black-box function $f(x)$. And the output modifies the quantum state ...

Wouldn't photonic computers be larger, not much faster?
I hear a lot about photonic computing as a possible alternative to transistor-based computing. However transistors are already much smaller than the wavelength of optical light. Wouldn't optical ...

Can we tell that the ability of computers to make a decision is based on a quantum property? [closed]
Can we say the ability of computers to make decisions is based on a quantum property? I refer to the PN junction in semiconductors, is the phenomena related to PN junction a quantum property?
Why I ...

Can computers recieve data wirelessly without being powered? [closed]
I'm not sure if this question totally fits here, but I think this is the best SE for it.
Traditionally, to connect to the internet (a server), a computer must be on: powered and running. This means ...

State Spaces in Classical vs Quantum systems, in the context of classical & quantum computers
I am currently reading "Quantum Computing: A Gentle Introduction" by Rieffel & Polak. In describing the difference between classical and quantum state spaces, they say:
In classical ...

Quantumly hard problem but classically easy [closed]
It is usually said that the quantum computer can solve classically hard problem but quantumly easy. See for example the Preskill video.
Are there important problems of the opposite: the classical ...

Why can't we search string vacua by computer?
I am imagining this:
A database of Calabi-Yau manifolds. More can be added when more are found.
The software picks a random CY manifold, assigns random fluxes etc. It looks at the low energy sector ...

Why are computers much smaller than they are fast?
In any medium there is a finite propagation speed at which information can spread. Special relativity provides an upper bound to that propagation speed, namely the speed of light in vacuum. Signals of ...
