Description
Encodes a \(K\)-dimensional logical Hilbert space into \(n_1\) modular qudits of dimension \(q\) and \(n_2 \neq 0\) oscillators, i.e., the Hilbert space of \(L^2\)-normalizable functions on \(\mathbb{Z}_q^{n_1} \times \mathbb{R}^{n_2}\). In photonic systems, photonic states of multiple degrees of freedom of a photon (e.g., frequency, amplitude, and polarization) are called hyper-entangled states [1].Cousins
- Qudit-into-oscillator code— A hybrid qudit-oscillator code with \(n_1=0\) is a qudit-into-oscillator code.
- Mixed code— Hybrid qudit-oscillator codes are examples of quantum analogues of mixed codes.
- Very small logical qubit (VSLQ) code— VSLQ decoder utilizes two ancillary oscillators.
- EA qubit stabilizer code— A minimal EA qubit stabilizer code has been realized in using hyper-entangled states [5].
