Quantum computer storage capacity - Physics Forums
Aug 10, 2022 · A qubit can only store one binary bit, or on the odd occasion, two entangled bits. 32 qubits can store 2^32 different possible patterns, but only 32 bits can be read at one time.
Does a qubit break interference in the double slit experiment?
Sep 7, 2025 · The qubit is a quantum object, so if the particle was in a superposition of up and down, the qubit can be in a superposition too. Measuring the qubit in an orthogonal direction might preserve the …
Schrödinger's Cat and the Qbit - Physics Forums
Apr 2, 2024 · If, on the other hand, the cat is truly in a superposition of “alive” and “dead”, then we have a quantum bit of information (qubit or Qbit). Let explain the difference between a Cbit and a Qbit and …
Number of qubits required for Shor's algorithm to factor a number
Apr 14, 2020 · Hey there, There are plenty of proposed implementations of Shor's algorithm which require different numbers of qubits, ##q##, to be able to factor a number...
Sending drive Pulse in CQED and visualize the state by QuTip
Jan 16, 2023 · In the dispersive regime, the qubit acts like a dielectric whose dielectric constant depends on the state of the qubit. This causes the cavity frequency to depend on the state of the qubit. When …
How Does a Qubit Exist as Both 1 and 0 Simultaneously?
Feb 11, 2024 · A qubit exists in a state of quantum superposition, allowing it to represent both 1 and 0 simultaneously until it is measured. This phenomenon is not merely an analogy but a fundamental …
