“…Additionally, ytterbium-171 ( 171 Yb) in particular offers a nuclear spin-1/2 qubit, available both in the ground state and in the metastable clock state for which the total electronic angular momentum is zero. In the past few years this nuclear spin qubit has been demonstrated [5][6][7][8][9][10][11] to offer long coherence times, fast and high fidelity gate operations, and high fidelity quantum nondemolition and "mid-circuit" measurements.…”

“…Second, 171 Yb offers a sufficiently rich level structure to allow us to choose which atoms participate in establishing remove entanglement -the "communication" qubits -while the others can simultaneously perform quantum computations -the "data" qubits. The "optical, metastable, ground" architecture 11,14,15 allows us to operate our atomic system as if we had two distinct atomic species 16 , thereby enabling the ability to simultaneously perform two sets of disparate operations.…”

In this Invited Paper, we will summarize our vision for quantum networks based on arrays of individual neutral atoms. With a photonic interface such as an optical cavity, some atoms in the array -the "communication" qubits -can establish remote entanglement while others -the "data" qubits -are used for large-scale quantum information processing or for quantum-enhanced metrology via an atomic clock transition. Deterministic gates within the array will enable operations and algorithms that are distributed among all the qubits in two or more nodes. Additionally, we will discuss our efforts to realize this vision with arrays of ytterbium-171 atoms in optical tweezers, in which telecom-band photons can be directly entangled with nuclear spin qubits without the need for wavelength conversion.

“…Next to being faster and non-destructive, the latter technique has the advantage that much fewer photons must be scattered for detection, reducing atom heating and cross-talk problems at the expense of serial readout. Parallel mid-circuit measurements of qubits have also been demonstrated recently [8,[80][81][82][83][84].…”

Neutral Atom Quantum Computing (NAQC) emerges as a promising hardware platform primarily due to its long coherence times and scalability. Additionally, NAQC offers computational advantages encompassing potential long-range connectivity, native multi-qubit gate support, and the ability to physically rearrange qubits with high fidelity. However, for the successful operation of a NAQC processor, one additionally requires new software tools to translate high-level algorithmic descriptions into a hardware executable representation, taking maximal advantage of the hardware capabilities. Realizing new software tools requires a close connection between tool developers and hardware experts to ensure that the corresponding software tools obey the corresponding physical constraints. This work aims to provide a basis to establish this connection by investigating the broad spectrum of capabilities intrinsic to the NAQC platform and its implications on the compilation process. To this end, we first review the physical background of NAQC and derive how it affects the overall compilation process by formulating suitable constraints and figures of merit. We then provide a summary of the compilation process and discuss currently available software tools in this overview. Finally, we present selected case studies and employ the discussed figures of merit to evaluate the different capabilities of NAQC and compare them between two hardware setups.

“…The beam geometry used by the JILA group involves vertical laser beams that trap the ytterbium atoms for their roles as data and ancilla qubits and horizontal laser beams that shuttle the qubits between ground (g) and metastable (m) manifolds.

Three research groups have exploited the nuclear spins of ytterbium-171 to manipulate qubits before they are read out-an approach that could lead to efficient error-correction schemes for trapped-atom computing platforms. By Tian XiaQ uantum computing on neutral-atom platforms has reached remarkable milestones in the past two decades. However, researchers have yet to overcome a key barrier to the realization of a neutral-atom-based quantum computer: the efficient correction of errors. In principle that barrier can be lowered with so-called midcircuit operations. These operations involve probing the quantum state of "ancilla" qubits without disturbing nearby "data" qubits used for computation. The ancilla qubit measurements can indicate whether the data qubits have undergone faulty operations, allowing for the data qubits to be corrected midcircuit-that is, during the execution of the computation rather than after its
