    Given its potential for integration and scalability, silicon is likely to be a key platform for large-scale quantum technologies. Individual electron-encoded artificial atoms, formed by either impurities or quantum dots, have emerged as a promising solution for silicon-based integrated quantum circuits. However, single qubits featuring an optical interface, which is needed for long-distance exchange

    Near-term applications of quantum information processors will rely on optimized circuit implementations to minimize the circuit depth, reducing the negative impact of gate errors in noisy intermediate-scale quantum (NISQ) computers. One approach to minimize the circuit depth is the use of a more expressive gate set. The XY two-qubit gate set can offer reductions in circuit depth for generic circuits

    The number of nodes typically used in sensory networks is growing rapidly, leading to large amounts of redundant data being exchanged between sensory terminals and computing units. To efficiently process such large amounts of data, and decrease power consumption, it is necessary to develop approaches to computing that operate close to or inside sensory networks, and that can reduce the redundant data

    The development of approaches that can efficiently control the magnetization of magnetic materials is central to the creation of fast and low-power spintronic devices. Spin transfer torque can be used to electrically manipulate magnetic order in devices, but is typically limited to nanosecond timescales.

    Flexible electronics can create lightweight, conformable components that could be integrated into smart systems for applications in healthcare, wearable devices and the Internet of Things. Such integrated smart systems will require a flexible processing engine to address their computational needs. However, the flexible processors demonstrated so far are typically fabricated using low-temperature poly-silicon

  • High tunnelling electroresistance in a ferroelectric van der Waals heterojunction via giant barrier height modulation
    Nat. Electron. (IF 27.5) Pub Date : 2020-07-06

    Ferroelectric tunnel junctions use a thin ferroelectric layer as a tunnelling barrier, the height of which can be modified by switching its ferroelectric polarization. The junctions can offer low power consumption, non-volatile switching and non-destructive readout, and thus are promising for the development of memory and computing applications. However, achieving a high tunnelling electroresistance

  • Power-efficient combinatorial optimization using intrinsic noise in memristor Hopfield neural networks
    Nat. Electron. (IF 27.5) Pub Date : 2020-07-06

    To tackle important combinatorial optimization problems, a variety of annealing-inspired computing accelerators, based on several different technology platforms, have been proposed, including quantum-, optical- and electronics-based approaches. However, to be of use in industrial applications, further improvements in speed and energy efficiency are necessary. Here, we report a memristor-based annealing

  • Reconfigurable logic and neuromorphic circuits based on electrically tunable two-dimensional homojunctions
    Nat. Electron. (IF 27.5) Pub Date : 2020-06-29
    Chen Pan; Chen-Yu Wang; Shi-Jun Liang; Yu Wang; Tianjun Cao; Pengfei Wang; Cong Wang; Shuang Wang; Bin Cheng; Anyuan Gao; Erfu Liu; Kenji Watanabe; Takashi Taniguchi; Feng Miao

    Reconfigurable logic and neuromorphic devices are crucial for the development of high-performance computing. However, creating reconfigurable devices based on conventional complementary metal–oxide–semiconductor technology is challenging due to the limited field-effect characteristics of the fundamental silicon devices. Here we show that a homojunction device made from two-dimensional tungsten diselenide

  • Creation and annihilation of non-volatile fixed magnetic skyrmions using voltage control of magnetic anisotropy
    Nat. Electron. (IF 27.5) Pub Date : 2020-06-29
    Dhritiman Bhattacharya; Seyed Armin Razavi; Hao Wu; Bingqian Dai; Kang L. Wang; Jayasimha Atulasimha

    Magnetic skyrmions are topological spin textures that could be used to create magnetic memory and logic devices. Such devices typically rely on current-controlled motion of skyrmions, but using skyrmions that are fixed in space could lead to more compact and energy-efficient devices. Here we report the manipulation of fixed magnetic skyrmions using voltage-controlled magnetic anisotropy. We show that

  • Sign-to-speech translation using machine-learning-assisted stretchable sensor arrays
    Nat. Electron. (IF 27.5) Pub Date : 2020-06-29
    Zhihao Zhou; Kyle Chen; Xiaoshi Li; Songlin Zhang; Yufen Wu; Yihao Zhou; Keyu Meng; Chenchen Sun; Qiang He; Wenjing Fan; Endong Fan; Zhiwei Lin; Xulong Tan; Weili Deng; Jin Yang; Jun Chen

    Signed languages are not as pervasive a conversational medium as spoken languages due to the history of institutional suppression of the former and the linguistic hegemony of the latter. This has led to a communication barrier between signers and non-signers that could be mitigated by technology-mediated approaches. Here, we show that a wearable sign-to-speech translation system, assisted by machine

  • Cars as a tool for monitoring and protecting biodiversity
    Nat. Electron. (IF 27.5) Pub Date : 2020-06-22
    Fernando Ascensão; Cristina Branquinho; Eloy Revilla

    Modern cars have an array of sensors that allow different objects to be recognized, including large and small animals. They thus have the potential to become a tool for monitoring biodiversity and improving driver safety. But to achieve this various challenges in computing, communications and privacy need to be addressed.

  • Promoting trust in self-driving vehicles
    Nat. Electron. (IF 27.5) Pub Date : 2020-06-22
    Cristina Olaverri-Monreal

    The adoption of autonomous vehicles will depend on the public’s trust in the technology. To establish such trust, it is important to understand the actions of different road users, and their reactions to the vehicles.
