A year ago, the Commerce Department blacklisted seven supercomputing entities for their association with the People’s Liberation Army. Further, there is evidence that the Chinese government has been stealing encrypted U.S. government and commercial data, warehousing it against the day when quantum computers can break today’s encryption. Quantum computing utilises quantum mechanical phenomenon such as entanglement and superposition to manipulate qubits to perform computation on a quantum computer. Currently available are tools to create and run programs on publicly usable quantum computers as well as resources to learn about them. As well as breaking the security of online transactions and communications… Read More

When measured, however, it yields only the classical result (0 or 1) with certain probabilities specified by the quantum state. In other words, the measurement changes the state of the qubit, “collapsing” it from a superposition to one of its terms. In fact one can prove (Holevo 1973) that the amount of information actually retrievable from a single qubit (what Timpson (2013, 47ff.) calls its “accessible information”) is no more than one bit.

Examining organizational requirements and developing strategic process models that facilitate the integration of quantum devices into organizational structures, therefore, constitutes an increasingly important research direction. Their interdisciplinarity and proximity to practice make Information Systems researchers particularly suited to tackle this problem in a way that provides practitioners with a helpful strategic framework. Quantum decoherence, sometimes also referred to as quantum noise, is the process of interaction between the quantum system and the environment, leading to the loss of quantum information (Shor 1996). Quantum technology depends on cooling particles with helium to maintain their stability. However, the limited supply and high… Read More

Topology is especially helpful here because many global topological properties are, by definition, invariant under deformation, and given that most errors are local, information encoded in topological properties is robust against them. Unitary gates manipulate information stored in the “quantum register”—a quantum system—and in this sense ordinary (unitary) quantum evolution can be regarded as a computation. In order to read the result of this computation, however, the quantum register must be measured. The measurement gate is a non-unitary gate that “collapses” the quantum superposition in the register onto one of its terms with a probability corresponding to its complex coefficient.… Read More
