What India needs to get through its covid crisis
With the humanitarian crisis in India worsening, immediate and aggressive measures are needed to stabilize the situation and buy time for vaccine production to ramp up. The crisis is already spreading beyond India’s borders and will require coordinated global action.
Speed is critical. As Michael Ryan of the World Health Organization noted in March 2020, “The greatest error is not to move … speed trumps perfection.” Over the past week, governments in countries including the UK, EU, Russia, and the US have pledged help, but they risk providing too little, too late.
Medical oxygen is in critically short supply in India, with an estimated daily need of 2 million oxygen cylinders far exceeding domestic production capacity. India also needs medications, hospital beds, ventilators, personal protective equipment, covid testing supplies, and other basic medical goods. More health workers may soon be needed to augment India’s own, who are currently working under immense pressure.
The US has pledged oxygen cylinders, oxygen concentrators and generation units, antiviral drugs, testing kits, and access to vaccine manufacturing supplies, and the first aid flights arrived in India on Friday, April 30. The EU has activated its Civil Protection Mechanism to ship oxygen and medications. The first aid shipments from the UK arrived on Tuesday, April 27, and included oxygen concentrators and ventilators.
Even this global aid response will not avert a historic tragedy. Projections show that we are likely to see over 12,000 daily deaths in India by mid-May, and close to 1 million total deaths by August.
That’s why Indian central and state governments must immediately enact aggressive public health measures to keep the virus at bay. These could include travel restrictions, workplace and school closures, and requirements for social distancing and mask wearing, along with social and economic support for the most vulnerable populations.
Such measures have been deployed inconsistently across India, and in some cases they have been undermined by political leaders. Multiple Indian regions, including Delhi, Karnataka, and Maharashtra, have recently imposed stringent travel and movement restrictions, but there’s still no national approach.
Ramping up vaccine manufacturing capacity, too, will be key to subduing the virus in India in the longer term and slowing its spread around the world. Doing that will require a coordinated global effort between companies and governments.
Slowly, the Indian government is starting to wake up to the situation. The recent advance purchase payments will allow Bharat Biotech to double its production capacity, to 20 million doses a month, by June and reach 60 million per month by August. Similarly, the Serum Institute hopes to be producing 100 million doses a month by mid-year. But this is not a near-term solution. Unfortunately, vaccines will not solve the acute crisis, and no major stocks of vaccines are currently available to import into India. Even the US pledge to share 60 million doses of AstraZeneca vaccine globally will take months to fulfill.
IBM wants to build a 100,000-qubit quantum computer
Quantum computing holds and processes information in a way that exploits the unique properties of fundamental particles: electrons, atoms, and small molecules can exist in multiple energy states at once, a phenomenon known as superposition, and the states of particles can become linked, or entangled, with one another. This means that information can be encoded and manipulated in novel ways, opening the door to a swath of classically impossible computing tasks.
As yet, quantum computers have not achieved anything useful that standard supercomputers cannot do. That is largely because they haven’t had enough qubits and because the systems are easily disrupted by tiny perturbations in their environment that physicists call noise.
Researchers have been exploring ways to make do with noisy systems, but many expect that quantum systems will have to scale up significantly to be truly useful, so that they can devote a large fraction of their qubits to correcting the errors induced by noise.
IBM is not the first to aim big. Google has said it is targeting a million qubits by the end of the decade, though error correction means only 10,000 will be available for computations. Maryland-based IonQ is aiming to have 1,024 “logical qubits,” each of which will be formed from an error-correcting circuit of 13 physical qubits, performing computations by 2028. Palo Alto–based PsiQuantum, like Google, is also aiming to build a million-qubit quantum computer, but it has not revealed its time scale or its error-correction requirements.
Because of those requirements, citing the number of physical qubits is something of a red herring—the particulars of how they are built, which affect factors such as their resilience to noise and their ease of operation, are crucially important. The companies involved usually offer additional measures of performance, such as “quantum volume” and the number of “algorithmic qubits.” In the next decade advances in error correction, qubit performance, and software-led error “mitigation,” as well as the major distinctions between different types of qubits, will make this race especially tricky to follow.
Refining the hardware
IBM’s qubits are currently made from rings of superconducting metal, which follow the same rules as atoms when operated at millikelvin temperatures, just a tiny fraction of a degree above absolute zero. In theory, these qubits can be operated in a large ensemble. But according to IBM’s own road map, quantum computers of the sort it’s building can only scale up to 5,000 qubits with current technology. Most experts say that’s not big enough to yield much in the way of useful computation. To create powerful quantum computers, engineers will have to go bigger. And that will require new technology.
How it feels to have a life-changing brain implant removed
Burkhart’s device was implanted in his brain around nine years ago, a few years after he was left unable to move his limbs following a diving accident. He volunteered to trial the device, which enabled him to move his hand and fingers. But it had to be removed seven and a half years later.
His particular implant was a small set of 100 electrodes, carefully inserted into a part of the brain that helps control movement. It worked by recording brain activity and sending these recordings to a computer, where they were processed using an algorithm. This was connected to a sleeve of electrodes worn on the arm. The idea was to translate thoughts of movement into electrical signals that would trigger movement.
Burkhart was the first to receive the implant, in 2014; he was 24 years old. Once he had recovered from the surgery, he began a training program to learn how to use it. Three times a week for around a year and a half, he visited a lab where the implant could be connected to a computer via a cable leading out of his head.
“It worked really well,” says Burkhart. “We started off just being able to open and close my hand, but after some time we were able to do individual finger movements.” He was eventually able to combine movements and control his grip strength. He was even able to play Guitar Hero.
“There was a lot that I was able to do, which was exciting,” he says. “But it was also still limited.” Not only was he only able to use the device in the lab, but he could only perform lab-based tasks. “Any of the activities we would do would be simplified,” he says.
For example, he could pour a bottle out, but it was only a bottle of beads, because the researchers didn’t want liquids around the electrical equipment. “It was kind of a bummer it wasn’t changing everything in my life, because I had seen how beneficial it could be,” he says.
At any rate, the device worked so well that the team extended the trial. Burkhart was initially meant to have the implant in place for 12 to 18 months, he says. “But everything was really successful … so we were able to continue on for quite a while after that.” The trial was extended on an annual basis, and Burkhart continued to visit the lab twice a week.
The Download: brain implant removal, and Nvidia’s AI payoff
Leggett told researchers that she “became one” with her device. It helped her to control the unpredictable, violent seizures she routinely experienced, and allowed her to take charge of her own life. So she was devastated when, two years later, she was told she had to remove the implant because the company that made it had gone bust.
The removal of this implant, and others like it, might represent a breach of human rights, ethicists say in a paper published earlier this month. And the issue will only become more pressing as the brain implant market grows in the coming years and more people receive devices like Leggett’s. Read the full story.
