One possible solution to the problem posed by the eventual failure of Moore’s law is to move to a different computing paradigm. One such paradigm is provided by the theoryofquantumcomputation,whichisbasedontheideaofusingquantummechanics toperformcomputations, insteadofclassicalphysics.Itturnsoutthatwhi...
The idea is that any correlations described by such a process admit a causal explanation, albeit one that may involve cycles. On the other hand, any process that cannot arise from a QCM in this manner describes correlations that are not amenable to an understanding in causal terms. The ...
Artwork: Optical computing: It's impossible to make quantum dots all the same size and shape, so they emit exactly the same wavelength (color) of light. But researchers have discovered how to to wrap them in other materials and shrink them, which effectively "tunes" thousands of dots of ...
Magic states are the resource that allows quantum computers to attain an advantage over classical computers. This resource consists in the deviation from a property called stabilizerness which in turn implies that stabilizer circuits can be efficiently s
In particular, for quantum computing, we need to store several independent identical copies of the corresponding qubits鈥攓uantum versions of bits. Storing qubit states is not easy, but it is possible to compress the corresponding multi-qubit states: for example, it is possible to store the ...
O0 is based on computing Boolean operations on n bits and is known to be implementable using O(n) gates. There are also two layers of n Hadamard gates. Both of these components thus require only O(n) gates per iteration. Because N=2n, it follows that O(n)=O(log(N)). Therefore,...

Perhaps the theory that proves to be the true explanation for quantum physics hasn't been posed yet. The person who poses it may not have even been born yet. But given the logic that this field of study has established, is it possible that all theories explaining quantum physics are all ...
Nevertheless, if the infidelity ϵτ ≔ 1 − 〈G∣τ∣G〉 is smaller than the target infidelity, that is, ϵτ < ϵ, then τ is still useful for quantum computing. For a robust verification protocol, such a state should be accepted with a high probability....
