For quantum computers to outperform their classical counterparts, they need more quantum bits, or qubits. State-of-the-art quantum computers have around 1,000 qubits. Columbia physicists Sebastian ...

Abstract: Designing sparse arrays with fewer antenna elements and lower peak sidelobe level (PSLL) is critical and challenging for antenna arrays in terminal devices in Internet of Things (IoT) ...

Abstract: In a sparse array, the holes in the corresponding difference co-array (DCA) limit the length of the consecutive subarray, which in turn reduces the number of achievable uniform degrees of ...
