چکیده
Neutral atom arrays are a rapidly developing platform for quantum science. In this work, we demonstrate universal set of gate operations on new type neutral qubit: nuclear spin in an alkaline earth-like (AEA), $^{171}$Yb. We present techniques cooling, trapping and imaging using newly discovered magic wavelength at $\lambda = 486.78$ nm. implement qubit initialization, readout, single-qubit gates, observe long lifetimes, $T_1 \approx 20$ s $T^*_2 1.24(5)$ s, operation fidelity $\mathcal{F}_{1Q} 0.99959(6)$. also two-qubit entangling gates the Rydberg blockade, as well coherent control these light shifts Yb$^+$ ion core transition 369 These results significant step towards highly AEA tweezer arrays.

Optimal Manipulations with Qubits: Universal NOT Gate
Classical information consists of bits, each of which can be either 0 or 1. Quantum information, on the other hand, consists of qubits which are two-level quantum systems with one level labeled |0〉 and the other |1〉. Qubits can not only be in one of the two levels, but in any superposition of them as well. This fact makes the properties of quantum information quite different from those of its c...
متن کاملQuantum tweezer for atoms.
We propose a quantum tweezer for extracting a desired number of neutral atoms from a reservoir. A trapped Bose-Einstein condensate is used as the reservoir, taking advantage of its coherent nature, which can guarantee a constant outcome. The tweezer is an attractive quantum dot, which may be generated by red-detuned laser light. By moving at certain speeds, the dot can extract a desired number ...
متن کاملUniversal quantum gates on electron-spin qubits with quantum dots inside single-side optical microcavities.
We present some compact quantum circuits for a deterministic quantum computing on electron-spin qubits assisted by quantum dots inside single-side optical microcavities, including the CNOT, Toffoli, and Fredkin gates. They are constructed by exploiting the giant optical Faraday rotation induced by a single-electron spin in a quantum dot inside a single-side optical microcavity as a result of ca...
متن کاملHigh-Fidelity Universal Gate Set for ^{9}Be^{+} Ion Qubits.
We report high-fidelity laser-beam-induced quantum logic gates on magnetic-field-insensitive qubits comprised of hyperfine states in ^{9}Be^{+} ions with a memory coherence time of more than 1 s. We demonstrate single-qubit gates with an error per gate of 3.8(1)×10^{-5}. By creating a Bell state with a deterministic two-qubit gate, we deduce a gate error of 8(4)×10^{-4}. We characterize the err...
متن کاملExperimental Time-Optimal Universal Control of Spin Qubits in Solids.
Quantum control of systems plays an important role in modern science and technology. The ultimate goal of quantum control is to achieve high-fidelity universal control in a time-optimal way. Although high-fidelity universal control has been reported in various quantum systems, experimental implementation of time-optimal universal control remains elusive. Here, we report the experimental realiza...
