Controlling the evolution of photonic quantum states is crucial for most quantum information processing and metrology tasks. Due to its importance, many mechanisms of quantum state evolution have been tested in detail and are well understood; however, the fundamental phase anomaly of evolving waves, ...
11a)162. These circuits provided a much more efficient way to create high-dimensional quantum states, enabling low and stable QBER well below both the coherent attack and individual attack limits. Moreover, measurement-device-independent (MDI) QKD, which eliminates all side channel loopholes in ...
In matrix notation, this results in the following: minx∈{0,1}𝑛x𝑇Qx.minx∈{0,1}nxTQx. (5) The connectivity of the qubits on the annealer’s topology limits the interaction between qubits; see Figure 2. D-Wave has proposed different topologies over recent years, such as the ...
Those limits were exceeded by including on-chip waveguide interferometers with variable phase shifters to precisely control the state of the qubits and to realize the entanglement of multi-photons directly on chip [30]. In the same year, the first Shor’s factoring algorithm proof of principle ...
They have the potential to solve very complex statistical problems that are beyond the limits of today’s computers. Quantum computing has so much promise and momentum that McKinsey has identified it as one of the next big trends in tech. Quantum computing alone—just one of three main areas ...

but it is intended to convey an idea: We now have quantum machines such that brute force simulation of what the quantum machine does iswell beyond the reachof our most powerful existing conventional computers. But these machines are not error-corrected, and noise severely limits their computationa...
An interesting protocol for quantum identity authentication on a basis of the classic shared secret has been presented recently (Hong et al. in Quantum Inf Process 16(10): 236, 2017). It requires few resources and it is technologically feasible. Its seminal analysis focuses on average eavesdroppe...
