Google Assistant now controls your Roku devices
Hey Google, save me the trouble of finding the remote.
After a few weeks of waiting, Roku’s promised Google Assistant control is here. If you’re using a TV or player running at least Roku OS 8.1, you can link the Google Home app to your Roku account and control core functions using only voice and an “on Roku” suffix. You can launch channels, search for shows and control playback on most devices, while TV owners can turn on the set, adjust volume or switch inputs.
The phrasing can occasionally get awkward — it’s not intuitive to say “hey Google, pause on Roku” when you have to answer the door. This won’t do anything if you prefer Alexa and other assistants, for that matter. Even so, it’s helpful for those moments when you can’t find the remote or want to launch a channel before you’ve taken a seat.
Google’s 49-qubit chip will allow them to develop a 49-qubit quantum system that can solve problems that are far beyond the capacity of ordinary computers: Google calls this goal quantum supremacy. The 20-qubit system that the Google quantum computing team is now working on currently boasts a “two-qubit fidelity” of 99.5 percent. The higher the rating, the fewer errors the system makes. Quantum supremacy demands not only a 49-qubit system, but also sufficient accuracy to achieve a two-qubit fidelity of at least 99.7 percent—which Google is on track to deliver by the end of 2017.
QUANTUM COMPUTING, QUANTUM SPEED
Google isn’t alone in their quest for advancing quantum computing. In 2016, IBM was running a 5 qubit computer, but by May 2017, it was offering beta access to its 16 qubit platform to the public for testing purposes. Furthermore, qubits alone aren’t the only consideration for actually achieving working quantum computers; error correction and scaling will also be critical to quantum systems. However, if Google does achieve quantum supremacy, it will be a major step forward.
