The $2T$-qutrit, a two-mode bosonic qutrit [PDF]

Quantum, 2023
Quantum computers often manipulate physical qubits encoded on two-level quantum systems. Bosonic qubit codes depart from this idea by encoding information in a well-chosen subspace of an infinite-dimensional Fock space.

Virtual Correlations in Single Qutrit [PDF]

Advances in Mathematical Physics, 2016
We construct the positive invertible map of the mixed states of a single qutrit onto the antisymmetrized bipartite qutrit states (quasifermions).

Amplified Quantum Correlation via Dynamical Modulation in Qubit‐Qutrit System under Markovian and Non‐Markovian Noise

Advanced Physics Research
We investigated the entanglement dynamics in a hybrid system subjected to a dynamical modulation amplification coupled to Random Telegraph Noise (RTN), which exhibits two distinct regimes: Markovian and non‐Markovian.

Qutrit Randomized Benchmarking [PDF]

Physical Review Letters, 2021
Ternary quantum processors offer significant computational advantages over conventional qubit technologies, leveraging the encoding and processing of quantum information in qutrits (three-level systems). To evaluate and compare the performance of such emerging quantum hardware it is essential to have robust benchmarking methods suitable for a higher ...

Intramolecular Charge-Transfer Dopants Enable Isolated Triplet Excitons as Spin Qutrits in a Single Crystal. [PDF]

Angew Chem Int Ed Engl
Photoexcitation of an intramolecular charge‐transfer molecule doped into single crystals of a structurally similar host molecule results in well‐ordered, spectrally addressable, and orientation‐tunable triplet excitons that maintain coherence at elevated temperatures.

Cloning a qutrit [PDF]

Journal of Modern Optics, 2002
We investigate several classes of state-dependent quantum cloners for three-level systems. These cloners optimally duplicate some of the four maximally-conjugate bases with an equal fidelity, thereby extending the phase-covariant qubit cloner to qutrits.

Qutrit entanglement [PDF]

Optics Communications, 2000
We consider the separability of various joint states for N qutrits. We derive two results: (i) the separability condition for a two-qutrit state that is a mixture of the maximally mixed state and a maximally entangled state (such a state is a generalization of the Werner state for two qubits); (ii) upper and lower bounds on the size of the neighborhood

Characterization of control in a superconducting qutrit using randomized benchmarking

Physical Review Research, 2021
We characterize control of a qutrit implemented in the lowest three energy levels of a capacitively shunted flux-biased superconducting circuit. Randomized benchmarking over the qutrit Clifford group yields an average fidelity of 98.89±0.05%.
