TECH FOCUS: QUANTUM COMPUTiNg Qubits and quantum computing: " more than science fiction " * Difficult combinatorics problems * Supply chain logistics * Finance markets * Drag development * Data analysis of large datasets * Weather prediction How can quantum computing help with these and other similar problems? The advantages are the result of the basic nature of information storage. The bit in classical computing has only two states: 0 or 1. For the quantum bit, or qubit as it is known, things are more complicated. The qubit is of physical size where the laws of quantum physics dominate and as a result it deals with the following phenomena: * Superposition * Qubit is in a state between 0 and 1 with certain probability * Its value is established during the measurement step * Entanglement * The probability state of the qubit is affected by the states of other qubits As a result of these phenomena, the size of information that can be stored in the qubit scales exponentially with the number of qubits N, 10 August 2022 Public funding in Quantum Computing since 2010 making it very suitable for the problems listed above. One of the questions that often arise is how the implementation of quantum computing in practice will be. There are many options for the design of qubits. One can expect specific problem-tailored computers. However, they will probably not operate independently, since they are not that good for classic control operations. Nor will they replace existing computers. One can expect that they will be connected to the classic computer, which will manage the operation of the quantum computer. This will be very similar to how GPUs work with CPUs today. The most interesting are the potential applications. Volkswagen is exploring the possibility of using quantum computers in the optimization of road traffic. They are investigating the perspectives for single driver or urban traffic planning. Ford is working on a similar problem, exploring optimization of the diesel delivery truck routes to reduce pollutants while also optimizing vehicle range. Toyota is trying to make progress on the design of solid-state batteries, the Holy Grail of battery design. This problem is very well suited for quantum computing since the phenomenon of consideration UPDATE McKinsey & Company
