In the quantum circuit model of quantum computing, we represent a quantum program as a sequence of gates, where each gate is an operation that changes the state of the system. Although easy to visualize and interpret, this representation of a circuit as a sequence of gates is not unique. Read more…
Can a single qubit store infinite information? Qubits are to quantum computing what bits are for classical (non-quantum) computing: they form the basic unit of computation and determine how data can be stored and manipulated in a computer. While each classical bit can store a value of 0 or 1, Read more…
Is Quantum Computing really parallel? This is one of those apparently simple questions that really made my head spin when I first learned about quantum computing. Many articles on the web claim that quantum computers can run high numbers of computations in parallel, solving problems in mere hours that would Read more…
