Canadian firm D-Wave Systems has calculated its way through a ‘topological phase transition’ using its 2,048-qubit ‘annealing quantum computer’. Several huge organisations have bought D-Wave computers – including Google and NASA (Lockheed-Martin even up-graded its D-Wave system) – but, in a world where folk are having trouble quantum-coupling a handful of qubits, there remain questions ...

Toshiba has introduced a bipolar driver for two-phase stepping motors up to 44V 5A that includes 1/128 micro-stepping. TB67S128FTG, as it is to be known, also supports full, half, quarter, 1/8, 1/16, 1/32 and 1/64 step operation – micro-stepping is by PWM, using sine-wave derived on-off ratios – output chopping frequency can be adjusted by external ...

Cliff Electronics has added a panel mounting BNC connector with a moulded plastic body to its FeedThrough connector range, all of which mount through the industry standard 24mm XLR panel cut-out. It comes in both 50Ω and 75Ω versions, and saves weight over the earlier metal version (~15g compared to ~28g). “The BNC connector is ...

C&K has launched SDB DIP switches, intended for low-profile applications where a long life cycling under load is important. There are through-hole or surface mount models, contact rating is 25mA at 24Vdc or 100mA at 50Vdc (at least, that is what the data sheet and website say) with electrical life predicted to be 1,000 cycles ...

Analog Device has created an impressively thin dual 10A dc-dc converter, that can also be used as a single 20A converter. Called LTM4686, it comes in a 16 x 11.9 x 1.82mm LGA package, which includes inductors and mosfets, but needs external capacitors. “The 1.82mm package height allows the LTM4686 to be placed on a ...

The way ants dig tunnels could help prevent collaborative robots accidentally slowing each other progress, according to Georgia Tech. The study, published August 17 in Science, shows that not all nearby ants attempt to dig a tunnel simultaneously. “We noticed that if you have 150 ants in a container, only 10 or 15 of them ...

Lithium metal batteries can be stabilised using ceramics, according to the University of University of Michigan, following the University of Texas announcement last year that glass can be used for stabilisation. Using lithium metal has the potential to increase the capacity of lithium-based rechargeable cells significantly compared with lithium-ion cells – Michigan claims doubling capacity. ...
