Millisecond Coherence Time in a Tunable Molecular Electronic Spin Qubit Full Record Related Research Abstract Here, quantum information processing QIP could revolutionize areas ranging from chemical modeling to cryptography. Abstract. Vanadyl phthalocyanine VOPc contains a highly coherent spin S = 12, which is of interest for applications in quantum information. Preservation of long coherence times upon deposition on conductive materials is crucial for use of single-spin in devices.

Conjugated Porphyrin Tapes as Quantum Mediators for Vanadyl Qubits.

A nuclear spin-free solvent, such as CS 2, T m approaches one millisecond at low temperature,29 showing that molecular spin systems can be as performant as extended inorganic structures. Unfortunately this remarkable long coherence is rapidly lost on increasing temperature because the spinlattice relaxation acts as a limiting factor for T. A nuclear spin-free solvent, such as CS 2, T m approaches one millisecond at low temperature,29 showing that molecular spin systems can be as performant as extended inorganic structures. Unfortunately this remarkable long coherence is rapidly lost on increasing temperature because the spin-lattice relaxation acts as a limiting factor for T. Aug 24, 2022 Qubits encoded in the nuclear spin states of alkaline-earth atoms are thus expected to have much longer coherence times than hyperfine qubits. In May the Berkeley-based startup Atom Computing published a paper describing its first-generation quantum processor, a tweezer array in which qubits are encoded in two nuclear spin levels of strontium.

Probing Nuclear Spin Effects on Electronic Spin Coherence via.

The spin degree of freedom of an electron or a nucleus is one of the most basic properties of nature and functions as an excellent qubit, as it provides a natural two-level system that is insensitive to electric fields, leading to long quantum coherence times. We review the physics of semiconductor spin qubits, focusing not only on the early achievements of spin initialization, control, and. Oct 31, 2016 Quantum information processing QIP offers the potential to create new frontiers in fields ranging from quantum biology to cryptography. Two key figures of merit for electronic spin qubits, the smallest units of QIP, are the coherence time T2, the lifetime of the qubit, and the spinlattice relaxation time T1, the thermally defined upper limit of T2. To achieve QIP, processable qubits. When nuclear spin-free ligands are employed, vanadium IV complexes can show at low temperature sufficiently long quantum coherence times, Tm, to perform quantum operations, but their.

. Jul 17, 2017 Though molecular electronic spins offer many advantages, including chemical tunability and facile addressability, the development of design principles for the synthesis of complexes that exhibit long qubit superposition lifetimes also known as coherence times, or T 2 remains a challenge. As nuclear spins in the local qubit environment are a. Among similarly investigated electron spin-qubits of vanadium, we note that the T m values observed for a frozen solution of VOdpm 2 are slightly longer in the whole investigated temperature range than those reported for a dispersion in protiated solvents at the same concentration of a vanadium complex with nuclear-spin free ligands.
