can only be observed up to 5 qubits [2]. In this paper, we wish to assess the quantumness and performance of the 16 qubit ibmqx5 device via the production of highly entangled states, …

We detect full entanglement up to 16 qubits, using an entanglement criterion based on reduced density matrices. Qubits are fully entangled in the sense that the state involves all physical …

Aug 12, 2024 · At the time of experiment, these include four five-qubit systems, five seven-qubit systems, one 16-qubit system, eight 27-qubit systems, three 127-qubit systems, and one 433 …

Once measured, the states of the entangled qubits are fixed, and repeated measurements yield consistent results. In this demonstration, we will explore entanglement using IBM Quantum …

Apr 25, 2024 · The device used for this experiment contained 16 qubits, arranged in a two-dimensional grid. The researchers carefully tuned the processor so all 16 qubits have the …

Apr 16, 2018 · Now, for the first time, the team has created a multi-particle entangled system that involves 20 qubits, which is a new record. What does that mean?

To determine that each pair of connected qubits are entangled, we perform full quantum state tomography on each quad – the pair and their neighbours – as described in the previous section.

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 have pushed …

May 20, 2021 · For the circuit show below, IBM shows that qubits 0,2 and 3 are "maximally entangled" with values of 0.5 (shown on the right with the three smaller black circles), while …

Oct 20, 2021 · Two recently published research papers detail the generation of a 27-qubit genuine multipartite entangled state and, separately, the generation of a 65-qubit bipartite entangled …
