A new method to correct for host star variability in multi-epoch observations of exoplanet transmission spectra
Vatsal Panwar, Jean-Michel Désert, Kamen O. Todorov +5
Transmission spectra of exoplanets orbiting active stars suffer from wavelength-dependent effects due to stellar photospheric heterogeneity. WASP-19b, an ultra-hot Jupiter (T$_{eq}…
Nonlinear quantum error correction
Maximilian Reichert, Louis W. Tessler, Marcel Bergmann +2
We introduce a theory of quantum error correction (QEC) for a subclass of states within a larger Hilbert space. In the standard theory of QEC, the set of all encoded states is form…
Ground-based optical transmission spectrum of the hot Jupiter HAT-P-1b
Kamen O. Todorov, Jean-Michel Desert, Catherine M. Huitson +6
Time-series spectrophotometric studies of exoplanets during transit using ground-based facilities are a promising approach to characterize their atmospheric compositions. We aim to…
Heralded creation of photonic qudits from parametric down conversion using linear optics
Jun-ichi Yoshikawa, Marcel Bergmann, Peter van Loock +7
We propose an experimental scheme to generate, in a heralded fashion, arbitrary quantum superpositions of two-mode optical states with a fixed total photon number based on weak…
A hybrid quantum repeater for qudits
Marcel Bergmann, Peter van Loock
We present a "hybrid quantum repeater" protocol for the long-distance distribution of atomic entangled states beyond qubits. In our scheme, imperfect noisy entangled pairs of two q…
Quantum error correction against photon loss using multi-component cat states
Marcel Bergmann, Peter van Loock
We analyse a generalised quantum error correction code against photon loss where a logical qubit is encoded into a subspace of a single oscillator mode that is spanned by distinct…
