Highly indistinguishable photons from a tin-vacancy spin qubit in diamond
Dennis Herrmann, Robert Morsch-Golsong, Tobias Bauer +9
Quantum networks promise secure communication, distributed sensing and modular quantum computing by interconnecting distant quantum nodes through photonic links. Extending such net…
Auxiliary Schmidt Rank as a Resource for Photonic Bell Measurements
Pradip Laha, Peter van Loock
In quantum communication and fusion-based quantum computation, photonic Bell measurements are fundamentally limited when only passive linear optics is employed. While for qubits, s…
Squeezing as a catalyst for non-Gaussian advantage in characterization of nonlinear media
Manju, Samaneh Hesabi, Siting Tang +2
We address the precise characterization of coupling strength of nonlinear media in continuous-variable (CV) quantum systems using coherent and squeezed vacuum states as Gaussian pr…
Bright-mode parity synthesis for bosonic state transfer through a single ancilla
Pradip Laha, Peter van Loock
Bosonic modes provide hardware-efficient quantum memories and logical registers, including highly non-Gaussian encoded states, but transferring finite-dimensional bosonic states th…
Squeezing-enhanced Pairwise Fusion of Photonic Qudits
Pradip Laha, Peter van Loock
Pairwise fusion gates are linear-optical measurements that herald Bell projections onto two-rail subspaces of two \(d\)-rail single-photon qudits. Without ancillary input photons,…
Picosecond Schrödinger cat states for ultrafast optical quantum processing
Mamoru Endo, Kan Takase, Takefumi Nomura +12
Non-Gaussian states are essential resources for universal, fault-tolerant optical quantum computing, but their generation rate remains limited by low heralding probabilities and op…
