Quantum entanglement is the phenomenon wherein the quantum state of each particle in a group cannot be described independently of the state of the others, even when the particles are …

In this paper, we report on the deterministic gen- eration of complex entangled states of 20 trapped-ion qubits and their partial characterisation via custom-built witnesses for genuine …

4 days ago · Controlling qubits with quantum superpositions allows them to dramatically violate a fundamental limit and encode information for about five times longer during ...

Jun 16, 2025 · While entanglement between 2 or 3 qubits is well understood and controllable, many-body entanglement (involving 10+ qubits) enters a regime that challenges even …

lored to the universal get set on ibmqx5. We detect full entanglement up to 16 qubits, using an entanglement cr. terion based on reduced density matrices. Qubits are fully entangled in the …

Apr 17, 2024 · Highest number of quantum bits in a single circuit-based quantum processor over time.

Oct 15, 2024 · Quantum computing companies are all working toward reaching 50 to 100 entangled qubits, a range that would allow quantum machines to solve complex problems far …

Jul 12, 2023 · More recently, as many as 27 qubits have been entangled in quantum computers. Now, Xiao-bo Zhu at the University of Science and Technology of China and his colleagues …

We refer to the users who are designing experiments with shallow circuits to fully exploit a large number of qubits as core users, and to the rest as standard users.

6 days ago · Google increased the number of qubits from 53 to 105 in six years. IBM recently revealed a 120-qubit design, and its latest roadmap suggests that it will remain a leading size …
