The emerging ﬁeld of quantum computing has been rapidly growing and has shown exciting opportunities to overcome the limitations of classical computers for many currently unfeasible problems. Quantum computers exist in the laboratory and are beginning to exceed 50 qubits, roughly the size beyond which their behavior cannot be predicted or emulated on present-day classical supercomputers. In this talk, I will present the proposes of quantum technology, its state-of-the-art, and its challenges. I will start with the basics and general descriptions of quantum physics. Then I will discuss the unidirectional signal propagation and routing, a key technology required for quantum computation devices. I will present our recent results on isolators suitable for quantum systems: quantum nonlinearity and new materials. I will first discuss the isolation effect obtained by combining quantum nonlinearities and symmetry breaking. Using an example of a two-qubit system, I will show that the dark state and its properties are crucial to establishing large nonreciprocity in this class of systems. We will discuss how two-qubit devices have been implemented as systems with an asymmetric dependence on the direction of the input ﬁeld, allowing them to act like unidirectional devices in quantum electronics. Then a novel approach to tunable isolation based on twisted bilayered Weyl semimetals will also be discussed. Finally, I will discuss the place of photonics in the quantum technology area.
