Anonymous quantum key agreement (AQCKA) is a related protocol which has been theoretically shown to obtain an even more substantial reduction in network resources when multi-partite entanglement is available and incorporated into the protocol.

The ability of these THz frequencies to cause nonlinear phenomena is of interest and has potential as a useful method of frequency conversion-leading to long term applications in electronic devices. Using 2D THz transmission spectroscopy [1]–[3] on THz generation crystals, we can generate and detect new frequencies of THz light.

Recent advances in optical wavefront shaping techniques have enabled controlling coherent light propagation in multiple-scattering samples. We overcome wave diffusion to deliver optical energy into a target region of arbitrary size and shape anywhere inside a strong-scattering system. This is particularly important for applications such as photoacoustic microscopy and optogenetics, where light needs to be deposited deep into biological tissue. For monochromatic light, we previously introduced the deposition matrix (DM) $mathrm{Z}(omega)$, which maps its input wavefront to the field distribution in the target region [1]. The eigenchannel with the largest eigenvalue provides the wavefront for maximal energy delivery. Since the enhancement is achieved via constructive interference of scattered waves, the optimal wavefront will vary with input wavelength.","PeriodicalId":19477,"journal":{"name":"Oceans","volume":"48 1","pages":"1-1"},"PeriodicalIF":0.0,"publicationDate":"2023-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87865763","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In contrast to dynamic phases, the geometric phase accumulated by a quantum system propagating through a Hilbert space $mathcal{H}$ depends exclusively on its path. In general, geometric phases can exhibit arbitrary dimensionality. Wilczek and Zee introduced the idea of multi-dimensional, non-Abelian geometric phases - so called holonomies [2]. Anandan later dropped the requirement of adiabaticity to create holonomies, that are truly time-independent [3]. Non-adiabatic holonomies rely on a subspace $mathcal{H}_{text{geo}}$ of the Hilbert-space that is spanned by states ${vert Phi_{k}rangle}_{k}$ that fulfill $(Phi_{k}vert hat{H}vert Phi_{j}rangle=0$, where $hat{H}$ is the system's Hamiltonian. Restricting the propagation to $mathcal{H}_{text{geo}}$ ensures parallel transport and, thus, a purely geometric phase (see Fig. 1a) [4], [5]. Quantum optics constitutes a particularly versatile platform for quantum information processing, and in particular for the construction of non-adiabatic holonomic quantum computers: In addition to integration and miniaturization provided by the platform, the bosonic nature of photons also conveniently allows for multiple excitations of the same mode, readily expanding $mathcal{H}_{text{geo}}$ and enabling the synthesis of holonomies from higher symmetry groups $mathrm{U}(N)$ as larger and more capable computational units [6], [7].","PeriodicalId":19477,"journal":{"name":"Oceans","volume":"32 1","pages":"1-1"},"PeriodicalIF":0.0,"publicationDate":"2023-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87971919","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To realize MPM, it is crucial to make maximum use of the nonlinearity of the excitation probability by using high intensity laser illumination. Most often, this is achieved by using femtosecond pulses from a mode-locked laser, however, these pulses suffer from chromatic dispersion and unwanted nonlinearities. Recent research endeavours are exploiting picosecond pulses as pulse-on-demand alternatives [2], [3]. Here, we utilize a Mach-Zehnder-based intensity electro-optic modulator (EOM), which splits an optical beam in two partial beams and induces a phase modulation in one of the partial beams by means of an applied voltage [4]. Being waveguide-based, a small driving voltage of 5V (TTL levels) are required to achieve a $(V_{pi})$ full modulation between constructive and destructive interference. To achieve short picosecond pulses expensive electrical pulse generators are required to provide the short picosecond electrical pulses. In this work we report on a driving signal employing twice the $V_{pi}$ voltage to generate ultra short optical pulses. As shown in Fig. 1, using a voltage of $2V_{pi}$ causes the EOM to jump between two states of maximal suppression in the short time of the rising or falling edge (80/20-times of 35 ps shown) with a very short open state of the EOM in between.","PeriodicalId":19477,"journal":{"name":"Oceans","volume":"27 1","pages":"1-1"},"PeriodicalIF":0.0,"publicationDate":"2023-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88433758","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
