The development of quantum computing systems has been a staple of academic research since the mid-1990s when the first proposal for physical platforms were proposed using Nuclear Magnetic Resonance and Ion-Trap hardware. These first proposals were very basic, essentially consisting of identifying a physical qubit (two-level quantum system) that could be isolated and controlled to achieve universal quantum computation. Over the past thirty years, the nature of quantum architecture design has changed significantly and the scale of investment, groups and companies involved in building quantum computers has increased exponentially. Architectural design for quantum computers examines systems at scale: fully error-corrected machines, potentially consisting of millions if not billions of physical qubits. These designs increasingly act as blueprints for academic groups and companies and are becoming increasingly more detailed, taking into account both the nature and operation of the physical qubits themselves and also peripheral environmental and control infrastructure that is required for each physical system. In this paper, several architectural structures that I have worked on will be reviewed, each of which has been adopted by either a national quantum computing program or a quantum startup.
The world faces a multiplicity of global catastrophic risks (GCRs), whose functionality as individual and collective complex adaptive networks (CANs) poses unique problems for governance in a world that itself comprises an intricately interlinked set of CANs. Here we examine necessary conditions for new approaches to governance that consider the known properties of CANs-especially that small changes in one part of the system can cascade and amplify throughout the system and that the system as a whole can also undergo rapid, dramatic, and often unpredictable change with little or no warning.
is a powerful tool that we as humans can choose to harness to create a better tomorrow.This is a precis of his talk.
The COVID-19 pandemic has had great economic impact on and yielded much information about the value of the performing arts.Most performing arts enterprises are not-for-profit, highly geared in the market, and require upfront investment ahead of uncertain returns.COVID-19 borders created special challenges for interstate and international co-productions and elite performers.Performing artists were hit especially hard during the pandemic necessitating rapid shifts in operational and funding strategies.A deep sense of isolation and loss of arts events drove a highly engaged uptake by audiences of digital performances, livestreamed and recorded, and public recognition of the central place that culture and creativity play in the daily lives of most Australians.The pandemic has driven adaptation and innovation in arts digital production and engagement with the expectation that this platform will persist post-COVID, potentially deepening and expanding access.Collectively strategising to strengthen the interconnections between arts and industries such as tourism and hospitality and retail, health, education and general wellbeing and cohesiveness of our community may well uncover opportunities for us to build back better.
B iometric recognition and authentication are crucial and gaining popularity in many security applications, including secure access control, human surveillance, suspicious activity recognition, border monitoring, preventing criminal acts, alarm monitoring and so on.Biometric recognition identifies a human identity based upon their physiological or behavioral characteristics, such as face, ear, fingerprint, palm print, iris, voice, gait and signature.Among these biometrics, the face and ear are considered as the most reliable traits due to their uniqueness and easy data acquisition.
