Floating qubit
In quantum computing, a qubit or quantum bit is a basic unit of quantum information—the quantum version of the classic binary bit physically realized with a two-state device. A qubit is a two-state (or two-level) quantum-mechanical system, one of the simplest quantum systems displaying the … See more The coining of the term qubit is attributed to Benjamin Schumacher. In the acknowledgments of his 1995 paper, Schumacher states that the term qubit was created in jest during a conversation with William Wootters See more A binary digit, characterized as 0 or 1, is used to represent information in classical computers. When averaged over both of its states (0,1), a binary digit can represent up to one bit of See more A pure qubit state is a coherent superposition of the basis states. This means that a single qubit ($${\displaystyle \psi }$$) can be described by a linear combination of $${\displaystyle 0\rangle }$$ and $${\displaystyle 1\rangle }$$: See more A number of qubits taken together is a qubit register. Quantum computers perform calculations by manipulating qubits within a register. See more In quantum mechanics, the general quantum state of a qubit can be represented by a linear superposition of its two See more There are various kinds of physical operations that can be performed on qubits. • See more An important distinguishing feature between qubits and classical bits is that multiple qubits can exhibit quantum entanglement. … See more WebMar 25, 2024 · We consider mediated interactions in an array of floating transmons, where each qubit capacitor consists of two superconducting pads galvanically isolated from …
