this comes at the cost of a reduction in entanglement. With a cap on the power, the maximum delay for which entanglement can be maintained is fixed. However, this limitation should not be viewed as a 'no go' for squeezedlight buffers because there are ways around it, which several groups are pursuing. Quantum information is not necessarily restricted to using qubits (two-state systems), because a photon is not limited to being in two states: it can be in more than two and in a superposition of

Marino et al. demonstrated that their quantum buffer could also delay quantum images, which can be thought of as a superposition of many transverse states -those encoding the spatial information of the light beam. Although others have recently achieved all-optical buffering of quantum signals 12,13 and classical images [14] [15] [16] [17] Marino et al. are the first to demonstrate the preservation of a quantum image (an image of the reduced Planck constant, ħ), noting the transverse correlations between their two light beams. With the hope of dramatically increased informationstorage capacity, it is likely that quantum images will play an important part in the future of quantum-information processing.
