The femtosecond laser direct-writing (FLDW) of waveguide circuits in glasses has seen interest from a number of fields over the previous 20 years. It has evolved from a curiosity to a viable platform for the rapid prototyping of small scale circuits. The field of quantum information science has exploited this capability and in the process advanced the fabrication technique. In this review the technological aspects of the laser inscription method relevant to quantum information science will be discussed. A range of demonstrations which have been enabled by laser written circuits will be outlined; these include novel circuits, simulations, photon sources and detection. This places the FLDW technique among the few integrated optical platforms to have produced individually every component required for scalable quantum computation.

“…In a QKD protocol, the random shared secret key is established first through a quantum channel and then utilized to encrypt the transmitted message between two remote authorized parties. Another remarkable research field, quantum direct communication (QDC) which includes quantum secure direct communication (QSDC) [9][10][11][12][13][14][15][16][17][18][19] and deterministic secure quantum communication (DSQC), [20][21][22][23][24][25][26][27][28][29][30] has also been developed quickly.…”

Fault tolerant deterministic secure quantum communication using logical Bell states against collective noise

et al. 2015

This study proposes two novel fault tolerant deterministic secure quantum communication (DSQC) schemes resistant to collective noise using logical Bell states. Either DSQC scheme is constructed based on a new coding function, which is designed by exploiting the property of the corresponding logical Bell states immune to collective-dephasing noise and collective-rotation noise, respectively. The secret message can be encoded by two simple unitary operations and decoded by merely performing Bell measurements, which can make the proposed scheme more convenient in practical applications. Moreover, the strategy of one-step quanta transmission, together with the technique of decoy logical qubits checking not only reduces the influence of other noise existing in a quantum channel, but also guarantees the security of the communication between two legitimate users. The final analysis shows that the proposed schemes are feasible and robust against various well-known attacks over the collective noise channel.

“…In 1999, Shimizu and Imoto [15] proposed the first DSQC protocol, and another DSQC protocol based on single photon two-qubit states was presented by Beige et al in 2002. [16] Thereafter, many advanced DSQC protocols have been already introduced, [17−34] including the protocols using the entangled states, [21][22][25][26][29][30][31][32]34] such as EPR pairs, GHZ states, W states, cluster states and so on, and the proto-cols employing the rearrangement technique of the particle order, [22][23][24][27][28]33] etc.…”

A novel deterministic secure quantum communication (DSQC) scheme is presented based on Einstein-Podolsky-Rosen (EPR) pairs and single photons in this study. In this scheme, the secret message can be encoded directly on the first particles of the prepared Bell states by simple unitary operations and decoded by performing the Bell-basis measurement after the additional classic information is exchanged. In addition, the strategy with two-step transmission of quantum data blocks and the technique of decoy-particle checking both are exploited to guarantee the security of the communication. Compared with some previous DSQC schemes, this scheme not only has a higher resource capacity, intrinsic efficiency and total efficiency, but also is more realizable in practical applications. Security analysis shows that the proposed scheme is unconditionally secure against various attacks over an ideal quantum channel and still conditionally robust over a noisy and lossy quantum channel.
