The sequential processing of qubits and the static nature of the compared data is the rationale behind the improvement. The introduced changes make that partial information gained in some authentication attempt gives the eavesdroppers no advantage in breaking the next ones. They are forced to consider...
Quantum information processing relies on the precise control of non-classical states in the presence of many uncontrolled environmental degrees of freedom. The interactions between the relevant degrees of freedom and the environment are often viewed as detrimental, as they dissipate energy and decohere ...
Let us recall the problem of Bertrand duopoly studied in [8]. In this case, two firms (players) compete in price. Let \(p_{1}\) and \(p_{2}\) be the prices chosen by player 1 and 2, respectively. Then, the product quantities are given by...
This method is general for realizing simultaneous interrogation of many parameters at and beyond the standard quantum limit, and could also be applied for other quantum information processing, e.g., quantum computing. Results The quantum Cramér-Rao bound of spectral measurements Let us consider the...
(116). Let us consider two simple cases. First, let us assume that the FRFT angles are the same for both down-converted photons: α=β. Then, no intensity correlation is observed whenever (132)cot2α=a−(a+2+b+2)−a+(a−2+b−2)a+−a−, where parameters a± and b...
Michio Kaku: Let's look at a classical computer calculating how a mouse navigates a maze. It is painful. One by one, it has to map every single left turn, right turn, left turn, right turn before it finds the goal. Now a quantum computer scans all possible routes simultaneously. This...
Quantum Entanglement and Information Processing 2.2 Quantum key distribution with entanglement Let us assume that the random variables X, Y and Z introduced above result from quantum measurements that Alice, Bob and Eve perform on a quantum stateψABE. It is clear for the quantum physicists, that...
Let |a⟩=|a1⟩|a2⟩⋯|am⟩ represent the fixed-point number a=0.a1a2⋯am (same for b). Using this representation, the quantum multiply–adder (QMA), as shown in Fig. 5a, can realize the following transformation, Πm,n±|a⟩|b⟩|c⟩=|a⟩|b⟩|c±a×b⟩, ...
The processing of information and computation is undergoing a paradigmatic shift since the realization of the enormous potential of quantum features to per
